It is no longer challenging. It's impossible. I have a lot of very powerful characters and usually a very good strategy. Previously the end would get challenging but not frustrating. Now it has me hurling profanities, rage quitting and wanting to hurl my iPad. I've tried various combos, startegies, orders, etc. and could not even come close to completing the last node of the last two GW attempts (and just barely the second to last node today) with plenty of almost maxed characters and plenty more others. I have 147 GW plays under my belt and attempt to finish it every day.
It does not feel "challenging." It feels frustrating, impossible and ridiculous. I generally can get a sense of when it's possible but hard. In the past I could feel that and would sometimes have to make many attempts before finding the right combo of skill and chance. Now it feels very obviously impossible.
