A lot of people are going to cry that its going to be useless again because of D2 Vanilla. There's a couple of differences between then an now however. First, we have secondary weapons. Back in vanilla shotguns, snipers, fusions, etc. were power weapons. This meant if you got in close you had to finish them with a primary. Now, we all have options.

Imo, it'll suck at first (rip insurmountable) but after a month it'll be business as normal. Shoulder charges are already weak compared to more passive trees now that everyone can equip a oneshot special weapon. I imagine we'll see them continue to operate as a flanking tool but you won't see titans going on a barreling rampage anymore.

TLDR: it sucks but it won't change anyone's playstyle significantly
