I like my summoner spellbook pose. it seems perfectly ready to call forth enchantments on my foes.

Dancer, on the other hand, I don't like their battle pose at all - not just because it doesn't look intimidating but because it doesn't at all look like they're poised to either dance or throw the chakrams.

Plus the "constantly in motion" thing looks awful in cutscenes. Monk has that issue too, but at least they look very ready to punch something.
