Hmm, well I guess some of my favorite maps could be considered small, like Salvage and Trailer Park. Part of my problem with these games is that most maps just don't work with every game mode. Especially when DLC comes out and they're shoved into every playlist.
My group always played HQ which does a pretty okay job of hiding map flaws. Now we play a bit of Domination and the flag placement in some maps like Sub Base, Radiation, Havana, Hazard, Drive-In etc. make them pretty annoying.
It feels like maps need to be a certain size to fit Domination flags and when you put them on a linear CTF/Sabotage/War map or an asymmetrical SnD/Demolition map or a tiny FFA map it's just awful.
I think maybe Treyarch's MP team just got War and Domination mixed up despite the similarity; what works as a War layout is just kind of shit for a Domination one.
