6-Star R5A Awakened Sig 200 Carnage was used for this solo.
The next boss has arrived and who better to solo her with than Carnage? Besides, Carnage actually fulfills the 2017 Objective that needs to be completed to get those juicy rewards.
He makes this fight a cakewalk not just by speeding through it with his damage, but also just by being able to spam a bunch of bleeds with the easy openings he can get for his heavies to be weaved in, so that it makes his damage just that more potent. Spamming heavies also minimizes the need to move around so much which helps in dealing with Reverse Controls if you aren't comfortable with them. Constantly knocking your opponent down with a heavy makes their AI far more likely to throw specials as well in my experience, so there's that too.
