I can't comment on the area. But your little rant/whine about powers was pretty weak.

I'm not saying ragers are overpowered, but you are complaining about restrictions on thirst? So there are drawbacks, it's a pretty sweet power(and yes, I have had a berserker rager since it's been changed).

To say that a rager can never compare to anyone who utilizes magic is hardly true either. Resistance, haste, and deathblow combined with someone with some ability is a pretty nasty thing.
