Well...you can be decently fast, but you lose a lot of power. If you want to go true hybrid, and be equally effective in melee and throwing, I'd recommend something along the lines of:
lvl 30
18/18
6 pt
6 ps
6 at
6 wm
4 free points
120 polearm
110ish throwing
It makes you effective enough in melee to beat those who you outskill or out-think, and effective enough in throwing to kill 2-h / polearm characters without melee if lucky. But you won't be master of either.
Though if you want to have a lot of fun...
Lvl 31
