Like, I wouldn't mind it either if SMN and RDM switched places where SMN is the support/utility DPS with less DPS than RDM, who'd have less support but more DPS, but that's essentially not the case. RDM right now has BOTH.

Anyway, nobody (or at least nobody sane) is saying RDM should be nerfed, but SMN needs to at least be on par or slightly higher in DPS than RDM because SMN at its current state is just completely outshined.
Also I really do not get RDM mains complaining about having the worst damage again if SMN gets buffed. You're going to be at a favorable level of DPS compared to back then where RDM was actually weak (and the DPS gap was just too high in general). I don't think it'll hurt if SMN was slightly above in DPS this time.
