P5AB misery

I've recently had the dumb idea to do P5AB. For some reason. It's literally the last thing I have to do on my save file for absolutely everything to be done. I've gotten 112%, done PoP, done Rad HoG, beat all pantheons with bindings, beaten GPZ all 10 times, beat White Defender all 5 times, given everyone possible Delicate Flowers without cheating and using save-and-quit strategies, gotten over 57 kills in the Eternal Ordeal, and beat P1-4AB. It's just P5AB left.

I've been documenting my playthrough and, so far, I've died 30 times in it. Of those deaths, here's who I died to"

• 5 to Vengefly King, mainly due to carelessness and rushing
• 2 to Gruz Mother, same reason
• 2 to Gorb
• 1 to Dung Defender
• 1 to Soul Warrior
• 1 to Oro and Mato
• 2 to Galien
• 2 to Collector (screw the minions not dying in one strike of Cyclone Slash)
• and 1 to Traitor Lord, the furthest I've made it.

But wait, you might say, that's only 17 deaths, where are the other 13?

7 are due to Oblobbles and 6 for the Sisters of Battle. This combo sucks. Oblobbles are a nightmare based on just how much of the screen they fill with their projectiles, and the Sisters of Battle are just evil. Sometimes, I'm just standing on the edge of the arena to avoid them from above and then they just spawn right on top of me with no warning to dash across the stage. This shouldn't be possible at all. The game should override this from happening unfairly. Winged Nosk, though I've only fought her once with AB, is a cakewalk in comparison despite me having no knowledge beforehand to help me.

I'm not here to ask for advice, just giving an update. Advice though is appreciated but not mandatory.
