I felt the same way with Monk.

Monk: 5% damage
PGL: 10% crit, 20 seconds of +20% damage. (MNKs can't use Archer abilities anymore)

So I basically leveled Pugilist to 30 so I could lose 1 CD, -10% less crit, take 10% more damage, and gain a few more skills that only really seem useful in PVP which isn't out yet.

Admittedly I should have researched the class a bit more before leveling it.. But the info was kinda hard to come by at the time.
