lol i have to dissagree, my casters rocked, i found no need for a cast of melee, i usually just needed a tank.
Yeah, well, that's because there really was no reason to push your effectiveness in any of these games other than XI.

impliment a nuker with less viability and effectiveness in battle?
Well, I would say that they should look for another way to make nuker viable other than simply make it compete for the top DPS spot.
