What I loved about Metro and Locker was the fact I could play those CQ maps however I chose - ie. I always had the option to participate in the meat grinder or flank around and either capture flags or decimate unsuspecting soldiers; these maps don't really give you that option and I foresee many people getting fed up with the sheer amount of snipers and MMGers riddling the air with bullets.
That's just my personal opinion; you're all free to enjoy the maps how you like. I will play the mandatory matches for that Commando Carbine and that's it. I thought they would have done more with this new mode after all this time.
