So I managed to beat two of the ultra hard Aqua shadow maps.
The last one with mass AoE just cut through all of my teams.

But what I meant to say is that after playing them I came to a conclusion that if you want to run a crit team on harder maps, it might be necessary to include a Negate girl in your team (Wolfberry). If her shield didnt absorbs the nuking damage from Sakura and Ume I would have not beaten that one. Same with Cactus.
Admittedly against AoE team its worthless since one Protea will take it down just by herself but still.
Also in these broken maps it seems to me that Counter teams do absolutely nothing as the uber buffed up Aqua shadows dont care about the counter attack.

As such having the shield to negate a single attack for a team that has like zero defense to speak off this is a huge deal. To bad there is not that many Negate girls and only Kuko has Crit. Habrntus has Negate but is a weaker counter girl (no super counter IRC) and I think there is one more from Promo girls, but I might be wrong.

Even if I had Rainbow rose up and ready to roll in my second crit team I think it wouldnt be enough. Actually this is the first time I am seriously considering Phoenix chan for the revival. But I dont want that girl so meh.

Just wanted to share my two cents about the progress and the possible tuning up of Crit teams.
