i dare say it certainly got harder.
still can pass it with my 45k wind main team (w/o stripping, a dancing girl team), thou lost a char in the process.
Think is, other than tendo, all the enemy are "slow", so there are things you can play around.

I used hinata for tanks, much better then kimmy here. the enemy damage are high enough that kimmy isn't going to grow much, and there are so many attackers that blocking 1 hit isn't enough.

hinata kurenai mei I think. Yes, they do punch through the shield SOMETIMES, but it's only SOMETIMES, my hinata can take a few hits to the face w/o help, and I've got both main's shield and kurenai's to help. With that, she usually lives to see turn 3, by which time half the enemy team is dead and I can win with 1-2 char losses(the continuous DoT from mei helps). I'm sure there are more effective teams, as it's just one of my standard team. Still, it's doable.

There probably aren't any solo tank that can tank the entire enemy team on that w/o any help of some sort (be it cc the enemy or weaken them or whatever), they be crazy.
