I have been spamming core Mirana and 3 charges of leap is going to be amazing.
To be honest the 6 month seasons is really what this game needed for me. I have friends who I used to play with that don't enjoy playing because they come back with too high of a MMR to enjoy themselves and the re-calibration may help with that issue. (Also turbo mode so that the game isn't a 1hr investment every time)
