Most of the time, plain maps finish with suicide charge from the loosing team, since they don't stand a chance and want to quickly switch to another map, with more "chances" of winning.
The new desert map with some low hills, provide absolutely NO cover for infantry. You have the choice between getting rolled over by cav, or pinned down by range. Or ganked by infantry, if you're one of the few spear+shield man.
Just add some trees, and i'll be fine with it, but NO cover sucks.
