I have encountered a player called *** many times now. He/She quits the match as soon as the match gets a bit difficult, or would even quit when there are low levels in our team. Doesn't even proposes surrender, just quits. It's frustrating meeting him/her knowing that the mission becomes futile. A report function in the game would be good too.
Please look into this MercurySteam, a frustrating step back to an already great game.
