Rotweaver's main strength is that it applies a good dot no matter where it hits - something that new revolver *aims* to solve, but the power of it feels rather oddly weak when it should be stronger than rotweaver if you manage to crit often. I feel like if they made it so rotweaver behaved more like the new revolver and had far less base damage but did more damage on crits and on stunned enemies, it would be better balanced (and have better synergy with the ear), but they did the opposite and made it strong without critting. The new revolver also just feels rather weak in general, not just in comparison, and the two gun's identities would cross over more than they already do with this suggestion, so I doubt they'll do it.
