Here are two tips for making your game easier:

1. In a team game (DOM, CTF or AS), use spectator mode to set orders. You can even fly around the map and order them to "Hold This Position"!

2. In a Domination game, use the "playersonly" cheat to freeze time, then capture all the bases, then turn the "playersonly" cheat off. This ensures a good few points for your team.
