A heroic events with the current crash bug is not something I ever want to do again. Limited rosters with frequent random crashing is a health pack drain and more frustrating than it’s worth. If I wasn’t so close to the CP I would have skipped the last sub.
Fortunately the crashing seemed to mostly occur during banners and ability animations, so goon fights and grinding the trivials got me enough points (my legendary token was Elektra purple–underwhelming, but still needed). Otherwise, about 1 in 3 or 4 regular battles ended in a game crash, even with closing all apps and restarting my phone frequently.
Hopefully they fix this sooner than later…or at least others are having better luck.
