Exile for Dominion, Ragnarok for Capture the Flag, & Haven for Regicide…
I mean come on people… there are other maps too… 
People just reallllllly like those maps. I get on average 1-2 meltdown games in Dominion every day, if that.
Yeah and a lot of the times the same map gets picked over and over and over. I played the same map 6 times in a row once. they should have a limit as to how many times the same map can be played in a row.
Problem is halo 4 maps are not very popular, Ragnarok, Exile and Haven are just popular with the community and considered good maps (exile i dont like) but thats just the way it is
