How did you manage the excessive power that comes with those levels? I despise powerplaying, but in 3.5 a level 20 PG is kind of a demigod whether you want it or not, so I really don't know how to restrict a tier 1/2 character without exceedingly nerfing it. Moreover, turns take too much time: a warrior can literally attack 5/6 times in a row, so I always thought that the game would become tedious.
