I've played WAR since relaunch and I love it.

So far only sucked at one dungeon, and that was because I didn't really get the mechanics on the first run. Have tanked nicely up to level 42, was loads of fun and I look badass. I only ever get real problems when I have too many adds to deal with at once. I think that's the same for PLD though, it's just practice.

Go for it. If you don't enjoy it after 25-30 levels and a few dungeons then just switch. That's the beauty of this game.
