GoW2 Multiplayer

I loved Gears of War. GoW2 is going to be the game that I'll be playing over XBL with my friends. Okay, it's still a mere 5v5 warzone instead of the 10v10/12v12 ones that I'd like to see, but with all the new stuff, it's going to be great. Especially the fact that weapons have stopping power is what appeals to me.

I often got defeated because people roll and run to me with a shotgun, instead of using tactics. In GoW2, you just spam them with gunfire, stopping them in their tracks. I can't wait!

EDIT: Bah, why doesn't it work? :S
