1st time playthrough with krieg. Currently using mania skill tree lvl 32 and got down to the beast and its pounding through tinas dlc. Hellborn or blood skill tree next? Also using a rough rider shield.
Whichever you find more fun. If you go with bloodlust you can do an explosive+ melee build, but hellborn also works just fine.
If you like blowing [censored] up, go with Bloodlust; otherwise go Hellborn.
