brownymasterEDIT: Also, we generally say no to pro_maps of stock maps. Except granary, since that map has been fucked with for so long like when they added gates then removed it and the lack of symmetry/spawn locations and what not.
And except koth_pro_viaduct, and then all the rest are custom maps designed for the comp community except gravelpit and badlands. I don't think there's anything wrong with making pro_ versions and they're often better, it just has to be done well. And on topic I don't think this is really an issue, lowering the time wouldn't add anything to the game imo.
