The tanking part of PLD is just fine. Most times I've tanked there was no enmity problems, but if you look at the whole picture the total dmg output from the PT is not worth it.
When you got a 6 DPS, WHM, Tank setup its kinda obvious if you wanna stick with the tank who deals 5k dmg or the one that deals 20k.

I even tried tanking Garuda on PLD, its really fine some blocks and self-healing really helps out, but it still just dosnt make up for the loss of 1 DPS. (When compared to WAR who tanks with little to none DPS penalty)
