Remember that when you
Epic Reincarnate, you do
not get to change your race or classes. So you will still be a BF pally @ lvl 20 unless you also
LR +20 into a different class(es). And because you're an Iconic, you can't
HTR at 20 like regular races. So you may wish to consider an
ITR instead.
Before giving up on paladin, spend some time in
Dreadnought (LD); in particular, once you get the hang of sustaining Blitz, suddenly it doesn't seem so bad anymore...
Otherwise, you may be ready to upgrade to BF Kensei, either pure ftr or ftr 18 / monk 2 like
Cetus. You lose the survivability perks of being a pally, ofc - high saves, extra self-healing, etc. - but gain some significant DPS thanks mostly to all the extra Melee Power in Kensei and One Cut's crit clickie.
