Love ya dexx, but hell no bro. I don't ever wanna see constant city maps balanced out with constant cave and tunnel maps ever again.
The only people that ever had a good time in them was 2 hander and polearm duelists with crossbows for back up. Dedicated ranged hated the maps that didn't have heights, because friendlies blocked their shots, and dedicated cav hated every single map in the rotation. At least on the open maps, infantry has to fight with their team instead of charging in and dueling people.
