Morshu
Truly Feared Pyro
This map is basically a harder version of dr_bearun, which has been in the map rotation for quite a lot of time now. I think having a new, harder version would make the map rotation a bit fresher and it would prove to be a new challenge to those who have already completed the normal version several times.
