MankyThere is reason why 5cp is most dominant gamemode in 6s.
Most of koth maps are ultimate dm fest, which makes game unfun to play and watch, as well sniper having insane impact on koth, especially on viaduct. Another major problem is that viaduct is only good koth map, and it's hard to make good koth map without ripping viaduct off.
idk about you but i think viaduct is one of the most fun maps to watch
its just hard to cast or understand if you are new
