Gees, this game mode pops up far too much in competitive. Maybe if we didn't have a bunch of kill-based competitive PvP quests I could find it more tolerable, but for solo-quers, the mode is simple hell.
4-stacks who are decently organized can just stomp a team in the saddest of ways. It's like the devs didn't think what they'd be mixing up when they made these decisions.
Competitive quests are hard for a good reason, but relying on the luck of the draw with matchmaking into the right gametype is just sad. This is a terrible oversight. That or the lead behind this is just out-of-touch with his customers.
