With that general poll being done on the forum which is exactly the place where 'the people that yell the loudest' are located, also containing an unrepresentative ratio of people that do not actually play and just vote based on nostalgia instead of actual experience, also more NA.
I don't think there is a fairer option than a poll on the forums - every person gets exactly one vote and the vocal people count just as much as the quiet ones. If it is public knowledge that map changes can be voted on then every player has the option to do so on the forums.
That's exactly the same as public elections in a democracy. People choosing not to go and vote forfeit their opportunity for change.
Horseshoe Canyon got re-added to the rotation last patch by me, it has been removed for ages and I dug up some old version from your ATS map pack and it might be flawed. You don't even want me to put the tower exactly the same walk time away from the spawns?
Thanks for going to the ATS files, there are a lot more maps in there that were just fun to play - if not balanced for every class. One of my personal (nostalgic) favs: Forest Bridge
Honestly, from my experience I have seen either team be able to get to the tower first, simply based on their determination and quick reaction at round start. Horses are also an option to use. Not sure if a change is needed - if it ain't broken, don't touch it.
