please buff the forgotten and nerfed champs

Dear Riot, your wonderful game League of Legends is special from other games in its genre because of its unique gamestyle and variety of champs

but some of these champs are just so weak and got nerfed then forgotten with less that 1% of players actually using them, they also dont appear in the champ rotation anymore

these include:

Kalista, mordekaiser, nunu (very old needs rework) and etc

so i beg and request you to buff them or make them unforgotten

P.S none of these champs are actually useful to me or im maining or using them, i only use kalista even though she is nerfed
