Dustbowl - Overall the best map in the game , its also the only map divided into 3 stages , which I like. It feels different than the rest of the maps , which is a good thing.
Well - One of the most hated maps , but not to me. Its extremely underrated . I really have no strategy though , because its rare that I see any servers open. So I suck when I play it.

Gravel Pit - While A is impossible to defend , and B is impossible to cap . I love this map . Any class works here , except for Pyros - but where do those work anyway?
Hydro - Another underrated map , the thing about this map is , sometimes I love , sometimes I hate it. So its in my bottom 3.
Granary - There is just something about Granary I don't like. No comment
2Fort - HELL
