What is your "My team are total idiots!" moment?

Pretty much whenever I see multiple people getting into the driver seat of a Warthog, and driving away without letting anyone be the gunner or ride shotgun.

Also whenever people use the assault rifle on Halo:CE as their main weapon.

Most matches, it seems. However, if you can't beat em, join em.

When the enemy team is carrying our flag to their base, about to un-tie the score, and team is sitting back at our base guarding it with all the turrets and power weapons. That's nice guys, but you do release they have our flag, right?

Going 30-5 and losing 50-37.

When my teammates keep rushing the enemy one at a time. I will try to make a plan for us and they ignore me and just keep handing the other team kills.

When my team quits at the start of the match because it was a gametype they didn't want.

Yep i was in the hornet on bloodline the other night and one of my teammates tried to betray me and a few other people he like shot us a few times and I taught him a lesson

When I'm sniping on Stonetown in the red base and my team opens the gate and then they leave and allow the other team to come barging in and overpower me

Every time I search H2A solo.

Teamate betrays me for sniper rifle when I'm about to kill the enemy sniper. He immediately gets killed and now the enemy team have 2 snipers and we're pinned down. We have SMG starts so we are screwed. Basically 15 free kills handed to the enemy team right at the start of the game. The teamate that betrayed me has -2 at the end of the match. My other two teamates have a kill count of 2 and 4. I have 17 kills. The other team got a Steaktacular.

Hip hip horray, I lost another game, because once again, my teamates were absolute idiots. Seriously, if you betray people for power weapons you are a ******* 5 year old.
