Why not add Light Rifle and Carbine to the mix?
I want SWAT Magnums, BoltSWAT, SWAT-Potato and more maps, honestly.
I never usually venture into the SWAT playlist, but more maps and varied gametypes might make me more inclined to do so.
Carbine and LR would be nice to toss into the mix as well. Especially for people having issues with the Carbine in the normal playlists.
