Made it. 509 and still got more time if I want to play more. May play a few more battles for rank, if it'll make a difference later. About 90 battles ahead of my defense, so I'm expecting a big drop. Win rate has been pretty abysmal, in the mid 80% range. Defense only around 10%, and only after putting MCR on the bench (was worse with her on defense).
Lots of good defenses, some I might have had better luck with a different set of toons. Got a lot of new ones with pulls from the Immortal event, Legendary souls from achievements and a few good rare souls. My roster is starting to look a lot more formidable. Hoping the RNGesus keeps smiling on me. Get my legendary from SQ's tomorrow, plus the event one, and the rares and g/a's.
