What i hear in this thread: Casters used to be the ultimate mega killers in game, now they aren't the top of the heap anymore, please bring back my ability to be number 1.
Melee was in a really bad spot for a very long time, now that they are useful for more than taking a hit to keep it off the caster so that it can kill everything, people that favor casters aren't happy. There are shrines, clickys, and pots for your spell points. I run casters fairly often, and I don't mind sharing the spotlight on the kill count with other people. I do fine with my spell point management, even on R10. I know the quests well enough to know where the shrines are, and make use of them if I'm going a bit overboard with casting. I'm not saying that changes can't be made, I am however saying that I don't see a major issue with damage output currently. If you're running R10, then consider putting in a group effort.
