Why is it you think that all mobs must be vulnerable to YOUR casters spell list/build what entitles you to be 100% effective versus all races and classes of mobs? Guess what kids there are going to be enemies out there you can't instakill, and some your acid savant can't cast acid on. What do you do when you fight constructs and undead you change gears and use some good ole fashioned damage spells. There is absolutely no reason to nerf these drow's SR it's one of their strengths and they should keep it to do otherwise would be asking for all mobs to just become one singular grey mob with average stats across the board that we all can kill the same as anyone else and would be boring beyond belief.

Leader of the Anti-Nerf campaign, do not let DDO become full of yellow foam stand up for mobs rights to keep what little power they have left.
