Playing a barbarian. at lvl 10th you get a choice of passive skill to increase health globe or increase crit and damage.
It seems like it would be an obvious choice, but my concern would be a tough one on one fight like with boss.
If health globe can generate during the fight and not just from a kill, then definitely have to get that skill. But if not, then you're sol and going to have to go with damage output.
What you guys think?
