Why can't we have the original Twisted Treeline for custom games?

Just about 95% of anyone who regularly played the Twisted Treeline back in season 1 will tell you how much they loved the original map. Well when I ask the question "Hey, do you like the current Twisted Treeline, or the original", well as you can imagine 100% of the 20 or so random people I asked said that the original Twisted Treeline was far better, and most of them even claimed that they refuse to play the current one out of spite of having the original taken away.

If we could at least have this map back into custom games there wouldn't be so much hate for the current map, which currently looks like something from My little pony with all its sparkles, glowing bright blue and pinkish lights, with shiny reflections on little rubies and stones scattered about. The map is just a disgrace to the shadow isles, and really killed the atmosphere of the deathly forest, plagued and imbued with magic and sorcery, that gave you the feeling of despair.

Well at least they added a spider? Right? Upvote and bump if you agree, this should be at the very least an option in custom games.
