I've never personally got "flack" just for being PLD before but do believe it can happen (I've gotting it for f'n up on mechanics as PLD thou) & personally I find PLD fun as the "sound" from 1 of WAR's main used moves gives me a headache & I couldn't figure out DRK before I f'd up then got chewed out by some rude ppl & gave up on it

the "Utility" of PLD has be helpful & saved my runs many times (Clemency'd the healer from dying to AoE's while they were stunned due to "Jackass boss" choosing them to much, cover+hallowed to cheese mechanics with co-tank in "crunch-time", etc.) just using said "Utility" at proper times & having ppl notice or apreciate it is the hard part (like that 1 time heal's was like "Oh I'm gona die & we'll wipe best give up & eat this sandwitch... wait WTF I ant dead damn u tank I'm eating!"... thou DPS did chew them out for complaining cause it was last boss of Dungeon & they could have just waited till they "Acutually" were dead, even thou 1 was SMN)
