I90 tank can tank anything in the game, (all ex Primal and T5 include) having parry focus is good but not a must. I gear my main PLD toward Crit and i tank T5 just fine. (Now a day i go for the look so i'm going with allagan armor. minus Head and weapon ;S) then again it so close to 2.2, just make sure u clsoe to i90 for the new content dont worry to much about BiS, it changing in 2 week anyway.
