At first I only liked Rush and Damavand Peak (because of the base jump).
I later got into Conquest, Team Deathmatch, and Squad Death Match.
I began to like all the original maps on Rush only.
I hated a few maps for Conquest, but adapted, then they became Okay.
My first impression of the Karkand maps were "Oh No", they look bland and feel weird.
Now I like all the maps equally as each has its own vibe and strengths.
