Best third for SHA/RNG?

I think I have it down to using those two classes for sure. Solo only. Want to be melee oriented dps beast, so looking at a melee third.

WAR - plate. Tanky. Probably solos best?

BER - zerk stance neat. But it doesn't work well at high levels because it's too squishy?

MNK - higher skills caps. Mend. New 10% haste AA.

PAL - triple divine invocation has advantages. 3x WIS caster. Ex mana class. Pal weapons. Plate. Tanky. Doesn't "double up" on triple attack like the rest. Feels potentially strongest, now that I type out the benefits.
