I started the topic cus of a major discussion on the trade chat of EU-Eonar yersteday and i just wanna clerify for people why 103.2% avoidance is not a viable goal.

First off i will start with BC.
In BC orange mobs (3+ level above you) could make crushing blows against their target making them take twice the damage. in order to avoid taking crushing blows you needed to avoid every single hit 1 way or another (block dodge parry or miss). the overall % you needed to become uncrushable was TADAA 103.2%.
Now in WotLK blizzard moved crushing blows from 3+ mobs to 4+ mobs because bosses were known as 3+ mobs.
The reason they removed it was because deathknights would be unable to survive a crushing blow like druids and would be unable to achieve 103.2% unless they went for pure avoidance. making them lose loads of health.
Besides it is hard to achieve then when you get 103.2% avoidance you still wont have 103.2% because blizzard added diminishing returns for WotLK to avoid another Sunwell Pleatue (which they failed at) so when you have 103.2% you will maybe only have 70%-80% (not calculated just threw something out).
For WotLK you need to balance health and avoidance. when you have 40k health unbuffed (as a shield wearer) you should have about 65%-70% avoidance (before diminishing). if you have this you will be ICC ready and should be killing ICC bosses. (both 10 and 25 man)
Ty for reading this. I hope people begin to move on from BC tanking cus now that we are in WotLK tanking is much diffrent. warriors now also got AOE tanking abilities. and every tank has the same chance to tank a boss cus they are just about equal in any way they can get without being equal (as blizzard states it)
