I'm not able anymore to play SC2 because it always crashes on startup with the error "An error occurred starting StarCraft II. Please try again. (Error 2: -2147483392)".
There is already a bugreport on WineHQ that seems to be fixed there: https://bugs.winehq.org/show_bug.cgi?id=40032
I'm running Ubuntu 16.10 64 bit and Crossover 16.1.0. Starcraft version is 3.10.1.
