Dragon Druid is a gross build and is OP in most situations. It could get hit with a nerf and still be decent.
That said, nothing on this server really needs to be buffed anymore for PvE. You can smash thru most PvE with an average strength build. You only need a god build if you plan to attempt to solo the Epic level areas. These god builds can get nerfed and they wouldn't hurt game balance, they would just make soloing the highest level content tougher.
Then again, perhaps BG is set in its ways with timed runs and knowing when certain high level areas reset, to the point where people are afraid if their god build gets nerfed, it will throw the clock off and other people might have the opportunity steal the riches.
