Treyarch's super tiny maps for Black Ops 2 tells me they're running out of ideas. I don't mind them borrowing from other artists/games. Just please stop making tiny postage stamp maps.
It's the tiny maps that's ruining the game by making spawning worse. I can't tell you how many times I've been killed seconds after I spawned, only because the maps are so small that spawning has fewer places to occur.
Dying seconds after spawning and increased camping is directly related to small maps. People cry about spawning close to the action, but the game is already designed to spawn players near teammates. And Treyarch and Infinity Ward can go farther and allow players to pick a teammate to spawn near based on where they are on the map. Battlefield has this and it works extremely well. Of course, there's always the chance that you'll get attacked sooner, too. But, at least you're given the choice of spawning near the action.
