What I'd really like to see for MA is the removal of the attack penalty on the fireball boon. Even it meant that the piety cost would have to go up a little bit, that would give MA a boon other than Refreshment that's worth taking.
I'd also like to see either the mana penalty reduced/removed for Taurog's boons or his death protection boon only require 2 or 3 of the items so that you can actually reasonably use it.
