Ah fair. I just kinda went with "haha, Ange goes brrrr" because I had most of the ops for that while specialist really relied on Weedy if I'm remembering right, who we of course didn't have for that CC.
Pretty much yeah. It really just stems from phys dps only being good against enemies with basically no defense or such high slow hits that defense is basically a joke. Part of why Mountain is so good is why Vigna is the best dp on kill vanguard till you hit Bag. Crits and really good self buffs, combined they pull fast hitting units into "big hits" range.
Likely that there isn't really much to explore in a game side from what they show in the source material. Doing a original story lets you use the set already made but it doesn't have to go the same limited way.
She is. Against defense crushers BP does 151 dps with S1, Rosmontis does 27 dps with no skill, 129 with s2 and 473 with skill 3, which is overall expected. It's hard to beat BP when it comes to chipping higher armor targets overall.
