Not shure if this has been suggested allready, but Ill put it out here in any case.

As the warriors recive a significant increase on hp the last ranks, why should the mages not recive it. As when one grows older, one grows wiser, and is often capable of concentrating longer and such. This would not be even a close comparison to benefit, but it would be a suited change to the mages in general.

And the prime stat for humans/half should be a general thing. Even mages are different. Not shure why this was not done in the first place, but Im shure there are some good reasons. But it would let people have more choices in the roleplaying aspect.

Love the game still...
