Don't stab me just coz I'm in your squad.
Why?
I prefer to play CODWaW (Domination) and at the start of the game, your team spawns in a little area that is close to one of the three flags. Once the game starts, some of the team sprints to the nearest flag to capture it. The more teammates caputring the flag just reduces the time to capture the flag. Everyone that captures the flag gets 15 points yet often there is some dork stabbing his teammates (or even shooting them). Since this is core (hardcore doesn't even have Domination) you can't inflict damge upon your teammates.
So, the question is: Why? Are they just making sure they remember how to melee? Perhaps they have unlimited ammo and are just warming up their gun? Am I missing something here? Maybe I should bash my teammates as well?
