the quickplay playlist is a serious downgrade from having objective and slayer separate, not to mention no ffa, koth swat etc which used to often be their own playlists.
Im not a fan of things like CTF and odball but having it all merged into one playlist forces me to play it when id rather play slayer (or one of the modes that isnt even there for some reason)
I see no reason why playlists cant be separated into catagories (swat, ffa, obj, etc) other than to just try and boost matchmaking speed
