Top 3 maps ...

[Apache Warrior]

Last night Italy was very lopsided. It can be fun if teams are equal, but when they aren't, I find T side tedious and CT side agonizing.
Remember when CS Source was in beta? The only map was Dust. By the time the game was released everyone hated Dust.
To many of the maps have to many choke points where one or two good players can stop a rush.

Italy is often lopsided and an AWPers paradise. They like it as much as Dust.
