Hi all, I've listened to all the feedback and enjoyed this thread a lot, it fostered a lot of good discussion. Even the people who can't voice their opinions without throwing personal insults provided some insight to the thread occasionally
I still absolutely believe that last hitting is an uninteresting mechanical skill, and that it brings about a boring first 10-15 minutes of this game.
I also recognize that champions and the current summoner's rift game mode have been balanced with this system in mind, so a document outlining four or five changes simply wouldn't be enough to create a fun and interesting system to replace it. Instead, it would need to be an entirely new game mode, such as Dominion. Personally, Dominion falls a little short for me, as they completely took away the base v base theme and made it round robin theme, but it's a good example of how you can't just modify a few things. The starting level, leveling rate, global gold gain, unique items, etc, etc all had to be tweaked and fine tuned to get anything playable and fun.
I dream of a new game mode in the future that has some the core concepts that so many people have talked about and liked in this thread, but I concede that remaking Summoner's Rift into this would have to be an entirely new game mode.
I will leave the two documents up for people's reference:
Doc v1: Proximity Based Gold Gain / Risk Zones
Doc v2: Pick-up Based Gold Gain / Assault Zones
Again thanks to everyone who made this thread so big, and thanks to the dev posts with your take on this subject. I think it got some wheels turning (at least mine) and showed there's support for the moba scene to grow this way in the future!
