When in power armor, the attack speed of using a two handed melee (slow) weapon has different attack speed while in 1st or 3rd person view.
(Tested with Super Sledge and Baseball Bat)
- When in 1st person view, the attack is exactly the same as when not in power armor, slow, two handed, and without any combo.
- When in 3rd person view, the weapon is held in one hand instead of two and attacks are much faster with a combo.
I'm not sure if this was intentional, but it seems like any melee build will have to switch to 3rd person view for max effectiveness.
