for 3 games in a row, for whatever reason, one of my partners would randomly get or not get the merc mode buff, and so he ends up being a hostile target and cannot receive heals. losing 20 points to random 2.2k scrubs each game because there's nothing we can do 2 v 3 v 1

just a warning.

merc mode works in arena? wtf?

not supposed to, but there's a bug that randomly gives your team merc mode buff when u join arenas.
