Haven't been around since 2014

I played the game avidly since 2010 but because of life and all that jazz I quit league back in 2014. With the new year rolling around and some of my friends who I originally got hooked to the game telling me I need to come back, I'm thinking of investing in a new PC as well as returning to Summoner's Rift. So for fun I figured I would see what has changed over the past year/year and a half! I have kept up so somewhat but when I was leaving Braum was just released, vayne was broken with the new item BOTRK, jungle sejuani and voli were my favorites, and teemo was still annoying as f**k.
