I feel like with how many other perks are giving you energy resistance you can forego perception and drop Refractor to 1. Use the 3 extra points for 7% damage bonus with Tenderizer (applies to teammates too)
I also feel that since you kill most things very quickly in one or two punches might also be worth it to get rid of Overly Generous and use those points for bigger damage boost through Adrenalin bumping it up to 3.
Most of the time you’re getting shot with physical ammo or being attacked by melee. Why over indulge into energy resistance when you could be doing 19% extra damage with these two changes
