^this... Chameleon even if it becomes more awesome is still on a LONG cooldown. So other than maybe saving the day if stuff just went horribly wrong, if things get so bad you need to use Chameleon in addition to the CNJ -enmity ability, well, the whole party is probably screwing stuff up royally. As I said before, currently, I only ever have had to use Chameleon when the party itsself was just learning (and therefore making more mistakes) how to do a new battle.
That being said, there's no reason not to learn it/use it if it'll make you a better mage. But you don't need to go out of your way ranking Archer if you have no intention of ever being an archer/bard. (I'm interested in bard so I've been ranking Archer in my free time.)
