I actually chose to max Knee Kick and Snap Shot for my Luke Raid build, while leaving Focused Fury at Level 3 for now. I find myself not using FF very often since there are quite a few hold-sensitive bosses. I mainly use it to hold a few of them to buy my party members a couple seconds to kill 'em off.
I also just finished Supercontinent today after transferring my top and crafting my shoulders, and my damage was kind of underwhelming at first, but…
I’m also pretty happy with the jump in damage, considering I felt awfully weak prior to today.
Definitely need some better enchants and amps at some point, but this’ll do for now.
