If you want ICC damage to be steadier, why don't you just walk over to the item team and say "Hey, we'd like less avoidance, can you cut out half of the avoidance from the ICC gear and replace it with stamina?" Or if you're worried people will get too much stamina, make it Frost Resistance and put in so much Frost damage you couldn't hope to survive long with TotGC gear alone.
We just don't think that works. If you put very unattractive stats on gear then players just go back the previous tier of gear and complain that we don't know how to itemize. If you put bonus stamina on the tier 10 gear, then that means the next tier of gear better have bonus stamina as well. If it has avoidance instead of that bonus stamina, tanks just shrug and go back to the tier 10 gear.
look at this line
if they are planing for a t11 then that meens a new inst before cat... as no one would go back to t10 if t11 was 5 lvls higher then it stat wize.if you put bonus stamina on the tier 10 gear, then that means the next tier of gear better have bonus stamina as well
