Precipice seems like a mistake, a decent red team will be able to stop anything but a high quality, coordinated blue team every time barring some unexpected series of events.
I really do not like how contracts work in casual mode. Once a team takes a lead, there's little motivation to help win the match, it becomes more important to let the match end so contracts can be finalized, however once people complete a contract they'd leave if it didn't require a round end so what do you do. Autobalance is not fairly done IMO. I get thrown into matches that end all the time. It detracts significantly from what used to be a fun time.
