The more I think about it, I'm not actually sure that the regen time is too long, 30 seconds isn't THAT long, and we need to have some time for the tactical aspects. I think what's happening is that the spells use too much mana. Especially if these are supposed to be the lower power spells in the game, we just can't fire off enough shots on a full load. As I said, this isn't a priority for me, but, when the time comes for balancing, I think dropping the mana cost of the current spells would do more good than speeding up the mana regen. (Though, further playtesting may reveal that I'm wrong or that we need a mix of both.)
