Guide to using TankPoints

TankPoints written by Whitetooth.
How to access TankPoints:
Once installed, TankPoints adds two
new panels to your character screen,
which you access here via the popup
menu.
Once there, you can mouse-over
each statistic for a detailed pop-up
window. Shown is the TankPoints
detail, which lists the values used to
calculate a TankPoints score which
is not very useful; this addon has
more important uses.
This is the Melee DR pop-up window. Very helpful
detail here.
It is the combat table from the bosses' perspective,
showing how hard you are to hit.
So a boss will miss me 9.2% of the time, I will dodge
24.47% of his attacks, parry 17.76% of them whilst he'll
hit me 48.64% of the time. I cannot be crushed or crit
(because I'm over 540 defence and the mob is L83).
Also are the values from +16 of each stat (most rare
gems come with these totals), so you can compare their
net benefit to you afterdiminishing returns. 16 dodge
rating gives me 0.3% extra avoidance, which is the best
avoidance per stat value. Look how crap strength is for
a Death Knight.

Diminishing returns on character panel.
This is often misunderstood because the GUI tooltip is
misleading.
The character panel, whether you have TankPoints or not,
displays your avoidance afterdiminishing returns. So it is
correct.
However, the figures shown in yellowin the mouse-over
window do notinclude diminishing returns (eg. the 9.58%), yet
the white title bar in the mouse-over window does include it.
So, I actually have 25.07% dodge.
My gear gives me 9.58% dodge (which is undiminished) and
you'd get from adding up all my armour items dodge rating.
Misleading.
Correct.
It calculates that my EH against
melee is 91K, which
automatically considers the
Presence (or Stance) I am in,
and any relevant damage-
reducing buffs you have up,
including trinkets.
It shows how armour (and
armour from Agility) and
stamina relate to your EH.
My base health here in Frost
Presence is 33414.
You have options to see your
EH against spell types too.
If I could not dodge/miss/etc for
example, my guaranteed
damage reduction from armour
and Presence is 63.45%.
Effective Health is TankPoints' second panel.

Effective Health whilst buffed
Here I have put up Blade Barrier (5%
damage reduction) and Vampiric Blood
(+15% health).
You can see my talent/buff/stance
reduction is now 10% in total, and my EHvs melee is higher from both talents too.
Spell damage reduction and effective health
You can find your TankPoints score when wearing your
resistance gear. I've put on my FrR and have 355 resistance.
Not very useful really.
However, you can see your damage reduction in total against
Frost (or other) spell types.
These panels come from a mouse-over.

Using TankPoints to help choose between equipment
Here I am comparing my equipped Furnace Stone (bottom slot)
and Figurine (top slot) with the Defender's Code in my
inventory.
The only time I f ind TankPoints score useful is in this scenario;
for an at-a-glance comparison of items.
Notice the Defender's Code has less TankPoints score than
both my top and bottom equipped trinket. That's useful to
know. It does have 0.34% more damage reduction because of
its 850 armour than my Figurine but overall it is not better.
Then you make a value judgement about the overall benefits
and situational usefulness. (I keep it for Flame Leviathan to
buff my iLevel but never use it otherwise).
You can configure what TankPoints shows in the tooltips via
its options window. Get it by typing /tp optionswin
The Stat Summary comes from the Ratings
Buster addon. You can configure what's
displayed by Ratings Buster via its slash
command.
It shows the absolute value of a stat (eg. the
1779 health from my Figurine) plus its relative
value to the top and bottom trinkets (in brackets
with a | between them).

Using TankPoints Calculator to help with difficult gear trade-offs and decisions
Click here to open the TankPoints calculator.
Action: To simulate a 22 agility cloak enchant, type 22 here.
Observation 2: the specific changes to the attack table from the
boss' perspective are shown here. You dodge more.
Observation 1: the changes are shown here to your effective health
(from the armour from agility), your total reduction (which combines
guaranteed reduction with your avoidance), and your guaranteed
reduction (again from armour). Your TankPoints score changes too,
which can be useful to write down if you are going to compare various
enchantment options.
Observation 3: your armour has increased from agility, so this
figures becomes green indicating its changed.
What if I put on a 22 agility cloak enchant?

Action: (1) Click [Defence Rating] to swap to [Defence], then since
we're removing Stoneskin Gargoyle we lose -25 defence skill. Type
that here. (2) Click [Parry] to change it to [Parry %] and enter 4.
Tankpoints understands these are flat ratings and not subject to
diminishing returns. In contrast, if we entered 50 parry rating, it
would be diminished in the calculations. (3) Not I did not enter the
loss of 2% health from Gargoyle in this example, just to keep it
simple.
Observation 1: since I did not add in the health loss, the changes
here are just the avoidance from the swap.
What if I swap tanking runeforges?
Observation 2: how your boss' attack table changes is the loss of
miss and dodge from defence (not they are exactly 1% because
TankPoints knows no DimRet applies), and the net gain of 3% parry.
Because we have not compensated for the loss of Defence skill (we
are at 519 now, you can see below), we now have a 0.83% chance to
be crit by the boss.

Notes
What are Diminishing Returns?
Simply that every gain of avoidance (dodge/ parry/ miss / block rating) is going
to be less of a gain the more you stack it. It means you cannot get to 100%
avoidance, because each new item of avoidance has a diminished gain.
This is possible because items come with, for example, a Dodge Rating. The
ratings don't change or get diminished, however what percentage (%) dodge
that translates into gets reduced.
The actual benefit you gain from an item therefore varies from one tank to
another, because your diminished returns are relative to how much of that stat
you already have.
Patch 3.2 onward
The screenshots in this guide were taken before 3.2, when parry had a lower
scaling per item point than it does now. In 3.2 onwards, parry and dodge gain
the same pre-diminished % avoidance as one another. However, parry
diminishes in value more quickly so dodge remains the superior stat on that
basis. You might find, depending on your level of gearing, that defence offers
equal or better avoidance than dodge, so remember to consider it for your red
gem slots.
The TankPoints score
The TankPoints score is derived from the
relationship between health and damage
reduction. It doesn't account for situations like
AOE, where dodge is more valuable, or how
the DK IBF buff scales with defence, and
other idiosyncrasies of tanking.
You should not use it exclusively for gear
decisions; however you can use the score to
help you choose between gear if you're
unsure about mechanics and theory.
For trinkets, collect them all for their
situational uses, and judge them
independently of TankPoints score because
they are the most commonly swapped in/out
item.
