Oof, yeah. The more I experiment with Shadowclone and Spirit Slash, the more I don't agree with some of the Winter Arcade changes. The Snow Frostlings move too fast, they attack too often and throw way too fast compared to before. You could see the snowball coming and sidestep it, even if you were fighting enemies. At least wisps didn't immediately run away from you, their shots weren't so fast you didn't have to constantly be moving to avoid them and perfect guarding them actually sent their shots back at them.
They've turned into mini-machinegunner bosslings that do a ton of damage, prevent you from focusing on any other enemy in the room and if they're hiding in a blizzard, good luck.
Doubly so if the entire room is slippery, or a couple of Thuglings are barreling down on you.
At least with whirlslash I can charge into them and try to kill them without a bunch of other Winter mobs descending on me. I'm giving up on that build for now, if not due to the Snow Frostlings then because of Marino. I'll revisit it whenever Marino winds up in the Hall of Memory.
