Also, just so you know, you miscalculated how many skill points and stat points you get from 1-99+quests. You don't get anything at level 1, so you only get 98 levels worth of skill/stats. That would be 110 skill points and 505 stat points.
if the point of this build is to have a blast owning nightmare it might be a playful experimental build. But I doubt you'll survive in hell. Also the need for 2 tanks shows the incompetence of the build. But as i said earlier, if your trying to have fun and play nightmare, it could be interesting. Good effort!
