It depends on what you mean by “help … at higher MH levels”. Do you expect it to lift a weaker weapon to the challenge? Do you want enemies to die in just a few shots? Are you otherwise those few weapons that rock MM10? Are you mobbing randomly across planets or are you doing time trials in the True Maliwan Takedown?
As an unprofessional Zane player, I just took it through Athenas at MM10 and it was fine: using a burly O.P.Q. System, taking my time behind cover, spent several magazines for some of the Cartel Underbosses and Badass enemies, less when kill skills were up… It would surely be easier with a Seein’ Dead, and I’m not sure the Conductor would help a MM0-locked mission weapon do much more.
Frankly I like it (at reasonable levels for me) because all the perks are on-point for this character: the buffs hit my weapons right, and it’s all Action-Skill duration modifiers are nice for the few weapons I have with, “while SNTNL/Action Skill is active…” anointments, but I make it a point to rotate COMs out regularly to keep things fresh.
