Achievement system

So i made another account, not to smurf and you know try hard/ruin new players experience but i wanted to learn more and practice going from absolutely nothing. What i was thinking about is having in game achievements that boost the amount of experience in the game. just outwardly playing a game and not doing objectives(like flash over baron pit wall 5x = 1000 xp or something). This could keep the attention of a lot of players especially when theyre achieving something, sometimes leveling up with the current system is simply so bleeding boring. let me know what you guys think. this would make the game that much more immersive.
