PLD will be a prog/newbie carrying tank.
Warr + DRK will be the meta for solid parties that don't need training wheels. Cuz Warr has been simplified by having abilities change with your stance, and has taken rampart from pld. And doesn't need to waste vengeance or raw intuition anymore for cleave stacks.

And now won't have penalty for changing stances.

I'd even say by then it'll be a simpler class to play than PLD.

So I advise leveling PLD now + a warr or DRK (for later). If you haven't already.
