Team Sizes

Does anyone find it obnoxious when you play a game of grifball or any other gamemode allows for more than the team size?

For instance in a 4v4 a group goes in with 5 and whoever is alone on the other team kills themselves . If this happens in grifball you get betrayed or he helps set up a spawn kill.

All im saying is wouldnt it be better to not allow a party size bigger than a team sizer per game type?
