Ascension 9 feels SO MUCH harder than anything else

I had 25% win rate until I reached A9 and the games I lost I still reached Glory a lot of times.

With A9 I'm losing constantly, even in Act 1.

I feel like A1-A8 could be harder and then the jump to A9 makes sense or A9 needs to be a bit easier, but the difference, at least for me with Ironclad, is extreme.

Does anybody else feel the same?
