Nicely-written guide; thanks for taking the time to write it! But are you sure GW difficulty depends on the power of your top 5? I keep reading that it depends on the power of the strongest Arena team you've won an Arena match with. In many cases that's the same five, but maybe not in all cases.
I am ftp, level 67, with just one 7-star toon (Biggs) but maybe a dozen g7/8 toons, and until yesterday I'd been clearing GW easily. Suddenly I've hit the wall at node 12 two days in a row. I wish the game would account for recent success/failure in GW to mitigate the sense of helplessness that can arise when you realize your top 5 have outrun your next 10.
