Fights are fun. I honestly don't mind the lower DPS check and infinitely prefer interesting and dynamic mechanics with good pacing like we've gotten over fights with tight DPS checks. There's a reason why TOP was absolutely miserable and why I dropped it when it first released. M4 definitely was undertuned in it's DPS check in my eyes, but I don't see how that is an actual problem. The mechanics are still difficult enough to me, the fights are fun.
There were plenty of new styles of presenting and resolving mechanics, but human brains are simply good at relating one thing to another. It's how I see the M3 player fuses as spells in waiting with different timers. Probably the most fun tier I've done so far and I hope this type of feedback doesn't lead to another abyssos situation.
