Re: For anyone who has Party Rose how is she?
I maxed Rose and Party Rose before GV (and obtained all Parties pre-GV as well), but even afterwards, she's still good. I run homing, damage and health upgrades on both. Party deals 8 per hit with damage upgrade, and 12 during Party Time with damage upgrade, which is still pretty good. I still prefer Party over regular tbh. Play her the same as before GV, just with more distance between you and your targets. If you can get the red crosshair, that's great, otherwise, a lot of target leading is required, but not difficult.
