You'll find a lot more destruction, verticality and pathways to your objective in the new maps. I really like them. But I play on servers now that have the lot mixed in and I don't mind any of the maps now (I play Rush all the time). Used to dislike Canals and Tehran Highway but I'm getting to grips with Canals and Tehran is ok now. All told, there is a nice varied selection of maps now, I even like Metro as a change of pace.
Would we say the new (old) maps are generally better than the new (new) maps?
