Frankly, none of the new maps are really that good. Besides, most of the community voiced their want of new guns, perks, gamemodes and camos. Very few said anything about new maps.
Besides, I'd rather have them spend some time to fix hit markers and commando than release maps that have way too many building, encouraging way too much camping.
Plus, WAW map packs were the shit. The new maps were usually well thought out, plus the new zombie maps were the ****ing best.
