From the LoL NA forums. It's an interesting idea. The document that talks about 4-5 changes and whatnot, it's the link in the post (it's a PDF).
I don't like:
-Removing last hitting (Will make the game worse and less involved imo)
-What it might mean for the jungle (Will it make jungling even worse of an option?)
I do like:
-Increasing rewards for tower destruction (Since early in the game destroying a tower isn't that good)
-Risk Zones (The further in your opponents base you are, the more gold/exp creeps give)
He talks about a different mode and keeping the current SR as "classic", however I think a few of the ideas should be added anyway. A red seemed to give it a good response too. So... .-.
