Pros/Cons of each Marauder build

Alrighttttt I'm convinced f3. I'm gonna save up nx and take 5 points out of drain and put em bak into shockwave. I won't d it til prbably mid 13x or 14x but I will eventually. The main reason I'm deciding to do it is because when Stransform is maxed, you can stay Stransformed half the time.

I won't be doin it now since drain is still my best single target attack. Its not like ill be losin much since points in drain don't add that much dmg

How come you're not taking the points out of Blast?
