Where to next?

I have a lvl 70 Marauder on Default and i have very low life(2000)


Any suggestions?

Meant no offense but your passive tree is quite messed up.
You didn't aim for the bigger life nodes. Even with free Respec points, it would be hard to respec that passive tree.

Look around the forums for a build that you want, modify it the way you see things and go from there. Well, good luck mate.
