If we look at a similarly small map like Grand Bazaar in Battlefield 3, it had an IFV for both teams. While I'm not against infantry only maps, I really don't think that the current vehicles on Cairo are so dominant that they diminish the infantry experience. In my opinion the reason why you'd want a vehicle on most maps, is to make sure that people who like to play Engineer have their part of the pie as well.
I have No Problem with Tanks, but when nonstop and more than one Tank is in Cairo, I quit Game and search a new one. It is unplayable because:
C is in Cairo important and there are Tanks, but no engineer to destroy the Tanks.
As medic I haven't Weapon to destroy the Tanks.
It sucks. Teamwork? In 1 or 2 Games of 10 maybe Teamwork exist.
