I would like to see a achievement system.
Something like :
* Play as support 500 games
* Make 10 pentakills
* Play with pantheon 400 games to achieve pantheon main
* Place 2000 wards
* Take the 1st blood 50 times
* Reach grandmaster elo
* Earn 300 non premade honors in 1 season
* Play 3 games in a row with perfect KDA
* Last hit 500 minions in 1 game 5 times
* Earn 25k gold 10 times
* Reach 100,200,300,500 lvl
* End the game before 15 min 10 times
etc etc etc...
for every achievement a reward
What do you think?
