Why? For some big CTF maps and max number of team players 15 minutes is just not enough for the game to become anything but carnage and those who capture the flag first are more likely to win. Just don't get, anyone who prefer shorter and faster games could play 15 min ones but for those who want more team work based game and use of tactics should have an option to play longer games. Another alteration that just don't make sense. :(((((
