It can help make the power inequality less blunt, sure. But a good, very good chunk of your effectiveness and how smooth your run is is very much based on what anima powers you accrue. Will you be able to get through [insert Torghast layer x] with the shittiest anima powers once you have good enough gear? Probably. But right now, you can have shit gear and skills and roll the dice just right to breeze through it while a guy with better gear can roll the dice and waste over an hour going through a slog of a layer only to get blueballed by a boss they aren't equipped to handle no matter how skillful they are.
And while I get that RNG is very much a part of that type of gameplay, I don't think it should be that influential that going into a layer is basically going "Welp, time to check if I'm lucky with this layer." I don't think that makes for rewarding gameplay for anyone except the people that have consistently been rolling good and can now pretend like they got through on pure unmitigated awesome gamer skill.
