What about more perma game mod, map or change the present?

Hi, I wanted to write about an irony of Lol who create mutiple new games modes and maps but can't do fixes to make more alive actual map ou actual game mode(Yes, i mean the Twisted treeline). You can find this map by clicking on "Play" then clicking to the right of Summoner Rift. Maybe some people would say: "Anyway i don't like playing 3s." Maybe if Lol could focus on this map as they have done on Summoner Rift as adding plants, modify turrets, Maybe then Twisted treeline could be funnier for everyone. Also, I wanted to share this old comment(from wiki lol) :

Interview about the map Marc 'Tryndamere' Merrill in an interview with Zam.com first mention the map:[6]

> So in regards to the new map,>>** which is one of the hottest items that we're really excited about**<<, we're about to roll one out. It's going to be going into the beta shortly. I don't know if it's in this release or if it's in the release at the end of the month. It's coming out really soon, it's a two-lane map, it's awesome, there's a lot of action, it's really well designed to force action to the middle of the map, and it's designed for a 3 on 3 play experience. So it's a very different experience, it will be a lot of fun for users to go bang away on that.

Also for those who do not know, the actual Twisted treeline is not the original map, there was another map before, if you want to look this map(that was way bigger than the actual one) search "old Twisted Treeline". In resume, how does developpers expect to make new perma game modes or perma new maps if they can't preserve or keep " alive" the actuals maps?(Remember Cystal Scar?) Maybe could a Rioter answer this question? Could Meddler post his thoughts on it?
