Even in QuakeLive where this bloody map is rewored so rail was moved in appropriate place, this map has never been used in any competition. Even in times when there were too few CTF maps, TA maps were used instead of this one in leagues. Even now CTF leagues mappool contains only 5 maps.
Q3 TDM leagues with 200+ clans were fine with like 7 maps, but OA needs 20+ maps for MAX 20 clans (OA Challenge had only 13 clans fyi), otherwise everyone will be bored to death We're so special.
I would understand if everyone wanted to play maps different from those that were played in Q3 for years. There're still lots of good but less popular maps. But why not orient on experiense of previos Q3 leagues with their rules, size of mappools etc, this is out of my understanding.
