when i say quick i dont mean a month from launch either. Swat,Snipers,Grifball now you show off grifball and the new stuff you can do and not make it a gametype at launch what 
Team doubles>Grifball>SWAT>Snipers in my opinion. They all need to be in there, team slayer pro needs to include oddball/king of the hill/capture the flag. OR create an objective playlist like in halo 3.
I totally agree with this. I would love Team doubles and Team Snipers. But I think they are going to wait until they Iron out ranks, because to be honest whats the point in playing those if there is no Rank. If I dont get rank I might as well play team slayer or Big Team Slayer because it give more XP.
You want grifball instead of rumble pit or doubles?
How can they do doubles there r only 4 maps small enough for 8 player slayer. Doubles is my favorite game type but guessin it wont happen til we see a lot of small dlc maps?
