Patch Available - GMS 1.37

I don't think it has to be this extreme though.

Me neither. Just chiming in here from what I've observed:

While Cygnus does encourage partying, part of what makes the change terrible is that anyone who used to steamroll V2s for mesos will have to upgrade significantly now to even get to the point when she summons them, and that's assuming they don't die to her Dark Genesis before then (To be verified, this would be less horrible if GMS' Empress has the KMS Dark Genesis). Furthermore, Bishops are one of the most useful supports you can get in there now due to Resurrection and Heaven's Door, except wait, hardly any Bishop would have enough DPS to clear Scrubby Garden if they're banished there (Since you need to beat all the mobs this time) and Holy Magic Shell doesn't protect against Dark Genesis either.

And to be honest, assuming you've got enough bind mules and DPS you could probably just keep binding her and attacking until she's down which is hardly exciting. I mean come on, 15 seconds to down an end-game boss, wow, how fun.
