I find my Power Armor build struggling to stack Enrage. Even if Hand Cannon and Shoulder Launcher is 20% chance to knock foes near target. (That is very situational i wouldn't recommend trying it at all.) Stacks often do not register when I clearly see them being knock back. I frantically use Chest Beam to make up before the stack hit zero but I still lose all my stacks anyway.
I noticed the same problem when using Pulverizer as an energy passive. It was so bad I swapped out of Molecular Self Assemble with other power on my tray that work fine. But I kept enrage for the growth and it sucks.
Could it be because im not using Strength? I'm using End, Ego, Dex.
