They are still the same ones but ND fixed the bad spawns.
In UC2, you can stand 10 meters infront of a spawn and people could spawn their, thankfully which doesn't happen in UC3.
Bad spawns happen in every game. If one person in the same team stands on each spawn, when an enemy spawns, it's bound to screw up.
What I'm trying to say is that UC2 spawns were a lot worse than UC3's. There is a reason they called UC2, Uncharted 2: Among Spawns.
I mean take a look at these two videos. Both were uploaded 2012+, way after the final UC2 patch in 2010.
This would never happen in UC3.
EDIT: Watch the 2nd video until the end, he does it twice.
I'm pretty much indifferent about most of the maps. However, if I had to chose my most hated map, it would probably be Dry Docks. Even though I sometimes get good scores, I hate it because it is just bland and dull. I usually lose when I play this map and I usually carry my noob teammates, which gets really annoying.
London streets and old quarters for crushing co-op.
+ Oasis. The siege goals on this maps are hell.
On competitive modes:
Fort: because the middle area becomes a death zone unless your party is owning. That restricts you to only use the underground parts of the map and the spawn points.
