I mostly just play on the hardest difficulty I can handle(heroic....) and make some of the weapons super-powered, usually the ones the enemies can use. It worked pretty well, since even if you know all the tricks to beat the AI, they're still insanely powerful.
Also, making all the enemies elites so they have shields works pretty well for training you to handle multiplayer.
