Interesting proposition. If it helps to boost vitality and xping, I'm all for it!
But I have questions:
1. Stats will be static for all classes after the transformation. I hope that doesn't mean that outside buffs, etc., are negated. Or are they?
2. Judging by the transformation spell list, everyone will become nukers. Will the transformation include a weapon, or will we continue to use whatever weapon we have in our possession at the time of the transformation? (I just can't envision archers casting spells with bows.)
3. This looks like a good event for healers and buffers. Why only a 60 minute transformation per account per day and no pets???
