I think MW3's issue was a lack of cohesion. There didn't really seem to be any play style encouraged by any of the maps. A lot of weapons suffered from the maps generally being large but very cluttered, though I can't speak for the DLC beyond the Face Off maps which (mostly) got the level design as good as it could be with MW3's spawn system.

The snipers were a problematic aspect to Black Ops in general, IMO. They suffered the most from Black Ops' rather lacklustre hit detection, and often times they just get hit markers. The map design didn't help, but at the same time it's not like snipers could ever really dominate unless you've got a twitch reactor with a WA2000.

Black Ops II, though obviously lacking in maps for snipers (beyond Yemen/Turbine and the odd DLC map), managed to make snipers work with the ill-suiting maps. I mean, it's a shame quickscoping is so damn easy, but hardscoping is actually a valid tactic so long as you're not trying to get mad scorestreaks.
