1. Forfeit button:
Nobody likes having their asses handed to them, and it is especially worse when it's you against 4 (cause your randoms suck and left/lagged out. A forfeit option, in the start menu, should be put in (even if it is only available in impossible situations, like 1 vs 4) to allow the other team to still get the win without the single getting completely curbstomped and soulcrushed. This is something I wouldn't expect in Reach, it's too late to code. Maybe we could see something in Halo 4 like this...
2. Why in God's name is "Team Hotshot" and "Power Slayer" in Action Sack? Heck, "Power Slayer" has slayer right in the name! These really belong in Slayer Playlists, if you ask me.
3. Grifball, and other sports, need their own K/D.
