Bringing back achievements to LoL

In the picture you can see a tab that shows the addition of achievements to LoL. Obviously Riot took out the feature of achievements before even letting it have a chance to breathe. I think it would add something to League such as something else besides champion mastery or season rewards, Now don't get me wrong the rewards for doing good in ranked, being placed well, and doing good with champions are very good and do their jobs by making me (the player) feel rewarded for my actions,but I feel there could be something better. I think it could just be something that could give a challenger player who might think that they have mastered League an extra innovative to play. Like one achievement would be getting Mastery 5 with all champs from Bilgewater, or getting mastery 5 with all Yordles. I think it would be a fun way to mix up things in the current state of League of Legends. It could make a player step outside their boundaries and try out new champs, new roles/lanes, and new play styles. Another thing could be getting a set amount of wins on a certain map or game mode (i.e. Normal,ARAM,URF,Ascension,Dominion). I know they have the badges on your profile for amount of wins,take downs,CS,Towers,etc. I just think it would be a cool addition to League, but I want to know how you view this concept. Please put any feedback in the chat below, and thank you for reading. Have a nice day.
