I do have a few suggestions to either point out, or correct, a handful of problems that seem to come up every couple of games:
1. Prevent people in parties/vent from joining the same game. This breaks the game and tends to ruin it for the other players.
2. Prevent cheese. This is a big problem in all maps, but it tends to be very frustrating on this map. For instance, a player joins and, rather than play, decides to just rush a random person or SCV rush people, etc. Adding destructible rocks at the entrances could help, or something else. It would be hard to prevent, but if it could be, that would rock.
Of course the biggest problem isn't something that can be prevented; people who attack without evidence (or wrong evidence) and discussion. Random violence tends to break most games.
