I really don't have the patience to sell ~50 or 60 gems. Don't really need the gold either. The way I figure it I can go a couple different routes.

1) Max Spelldamage (this is what I am currently speced at)
2) Max Haste
3) ~40% crit. I think I remember reading that you want 40% crit as to try and keep the mana reducing ability up as long as possible
4) Max Stam
5) ??
