For the love of...: COIN IS UNHEALTHY FOR THE GAME RN
Like holy fucking moly. It gens too much damn gold. Support itemization isn't exactly tooled with the notion in mind that we'll be running around full build by 30 minutes, before anyone else on our team. It was tooled to be pretty damn effective per item, but slow to build because supports didn't have a ton of gold rolling in. If support gold is going to be significantly higher than before, then we have to retool how we work support items into the game, especially support items that serve to be "early game buys" like Censer. Remember: There was a time where Censer was as strong as it was AND Redemption + Locket was nerfed, but Janna wasn't rocking a massive win rate/play rate/ban rate, Sona had a 51% - 52% win rate and didn't use coin at all, and THRESH was the big deal in bot lane. What changed? THIS MOTHER FUCKER RIGHT HERE. 
If we AREN'T going to remold the role around getting more gold and building items more freely: FOR THE LOVE OF TEEMO NERF COIN'S GOLD GEN
