Patch 7.16 brings us closer and closer to the World Championship patch. With just two more patches before the one that really counts, Patch 7.16 is all about setting the table for some big changes to come.
What that means for most people is that any champion that was incredibly strong or way out of line is getting a nerf this patch. Champions that were getting banned in most games like Caitlyn, Orianna, Galio and Maokai are all recieving some a nerf or two to help set them right with the rest of the game.
Also getting a little toned down this week is the entire Ancient Coin line which was helping champions like Janna become an absolute terror at support thanks to never having to worry about mana. In the jungle, the biggest change this patch comes in the form of a cost increase on Cinderhulk that should help the other jungle enchantments see a little more use.
On the plus side, Riot finally added a vision ping, so you can stop pinging danger on warded brushes and scaring the rest of your team.
