League lacks rewards that make you feel special (or rewarded)

The only icon I got that felt like a big deal was the shurima one from Ascended game mode.

Why we don't have more of it? I play mostly League ARAMs now and it'd be so nice to have things to strive for, or to feel good about, like something permanent in your account other than the champions and the friends you don't talk to anymore.

Stuff like

"Get a firstblood in the first minute" - 5th getting the achievement, number of people who got it, some 'rarity' stat to it.

"Die 0 times as one of the following useless champions in the current meta ___, in a match"

Jhin special achievement: "Don't be a fucking douchebag, you walk really fast and look really cool"

Ya'know something that would make u feel reaal rewarded
