I'm personally fed up with Halo 2 all together...I had it 2 weeks before it came out, got XboxLive, and..I dont know, they stressed the team thing a bit too much, somehow i got more pleasure out of owning 6 noobs w/ pistol...
I just want Halo 3 to have a decent ending for campaign, and multi to not be..sucky

I'm not quite fed up with the game, but I agree with you. And personally, I think the "tribe" ideas suck. No offense...
And about bots...yes, that would be awesome, but how would they get the AI to work over the internet, or LAN? If they did have it, it would probably only work on split-screen.
