The HOTA Barb has felt consistently powerful at every level. It’s particularly vulnerable against ranged enemies but in a crowded room it’s just unstoppable. Not a lot of finesse though. icyVeins has a good guide for level 1-50 and then maxroll.gg was good for tier 3. I’m undecided what to do for S1, definitely want to try something new though.
