As someone pointed out in my "Make melee into massively powerful gesault characters" thread, the problem isn't one that can be fixed via a simple change in the scale of power of melee.

The problem is casters are batman, and melee are not.

Casters start getting "save or die", "save or suck" spells at a certain point.
They also get "mass save or die" and "mass save or suck" spells.
They also get "suck even if you don't save".

The power ratio change from the "suck" spells is huge -- and once you make someone suck, you don't have to be all that powerful to destroy them.

I suppose you could set the game up so that melee are insanely better at some realm -- but practically, the only domains melee can outpower casters is damage (in the short term) survivability. So if you follow this route, you can make blaster wizards completely obsolete... but blaster wizards aren't the problem.

Changes like the above could, for example, deal with CoDzilla and her brother DoDzilla, the overwpowered melee-based cleric and druid.
