Tanking in Coil as a WAR is like shooting yourself in the foot and trying to run a mile, can you do it? Probably but it will hurt and take exponentially longer. Dunno if Lodestone still has me in the HQ crafted MNK stuff I made, but I have a few ilevel 90 tank pieces, 6k HP as PLD, and 7600ish as WAR (in group). I don't think that WARs need a buff, but that PLDs need to be nerfed. We are missing an entire gear level (ilevel 80 from CT) and PLDs can waltz into coil and take down the first 4 turns with relative ease
