Well, I think we all can (and already have) gone through the "this name stinks, I wish it was X" game. Heck, I went through it back before PHI with the whole "I don't like having both a 'warlock' and a 'warlord' as names" thing. Throw in the 'warden', and I still occasionally wish they had named the warlord 'marshal', even though it really doesn't affect my enjoyment of the game or class whatsoever.
Am I crazy about the name 'battlemind'? No. Do I like it heads and tails above 'psychic warrior'? Absolutely. And I'm much happier with 'battlemind' than 'warmind', which had been suggested way back as an idea when the psionic power source was first announced. A fourth 'war' named class and I really would have rolled my eyes.
Heck, in my perfect world, they would have kept the name 'Empath' rather than 'Ardent', because I find it more indicative and evocative of the power source it represents. But at this point we just start getting nitpicky and splitting hairs, and it really becomes nothing more than personal preference.
