There are a few good PLD's out there, but many many more bad 1's, and to varying degrees. It sounds like you got 1 of a lower skill. PLD does have a bit more mitigation and survival compared to a WAR, but it doesn't make a superior tank as ppl had hoped for. I have both WAR and PLD leveled and from my experience WAR has its "squishy" moments. When I'm out of cd's on WAR, well i'm out, PLD always seems to have a trick up it's sleeve. The key does seem to be like you said, management of cd's and mp, as well as getting out of AF gear into double/triple melded cobalt asap. AF gear, sadly imo, is complete trash. The way it should work is PLD has mitigation and should either A) stack more mitigation to reach a "cap" or B) stack hp to bridge the gap between them and WAR's. Where as WAR can either stack more hp, or more dmg output as this is directly tied to their survival. just my 2 cents
