And yes, there wouldn't be sight towers everywhere. I imagine there'd be none in the jungle. That said, the map would be substantially overhauled to support the towers and so the need for wards could be lessened.

I might do a doodle later and Twisted Treeline-ify Summoner's Rift, just to see how it'd work.
