Y'all remember when Corki was actually a champion?

Yes, when he was a botlane marksman before the ADC's rework that forced him into Midlane.

He has a 50% WR with a Delta(mains/people who play him very often) of 56%. I am confused as to what is wrong with his performance. If possible could you enlighten me?

The best argument i could see is that he is not that interesting or fun.

yes

I remember those Leona/corki botlanes in season 3 and 4

/shudders

nah i remember whne corki was good, that boy woud kill u with a +auto and if u were still alive he would r and and auto 1 more time. before riot reworked him he was busted af but he has never been popular because his kit and corki himself are unattractive.

who?

TBH Corki is fairly strong it's just that he has so, so many bad match-ups anywhere he goes.

They should give him a VFX update as well as a new model.

Corki is fun and not that bad his kit is actually not that different from lucians.
