I haven't played in like a year, what happened?

Basicly the whole game just got more damage into every role. Except adcs. ADCs went from being the best role (together with the support) to the worst role with least hp, least basestats and and of the lowest dmg. Also Riot did some terrible champion design choices :D Broken new and reworked champiosn every where.
But the game still does a lot of fun somehow.
