Altis looks great and I really like the new building types. There is however one small thing about the Kavala hospital I would like to see changed.
At the moment only the ground floor is enterable. I think it would be great if at least the top structure, near the helipad, with the sliding doors was also accessible.
It would create a interesting end point for air ambulance or combat rescue missions. Delivering your patient into the hospital, instead of just dumping them outside the door.
