I personally always saw RDM as the master of both Enfeeblement AND Enhancement. I agree that melee only needs small changes to make it acceptable, but when looking at RDM's role as an enfeebler, we should also consider the enhancement role as well. Specifically, where are the gain-ras, or other buff spells that could help an entire party and make RDM relevant once again without changing the dynamics of other classes? After all, RDM has the highest (initial) Enhancing Magic skill too.
