ekko ult is glitching HARD

ok so everyone who has seen or played ekko knows how his ult works. OK so here is what is going on when you ult with ekko your supposed to go where ekkos hologram/paradox was 4 secs previously but as of now when you ult you are sliding a little back wards then you freeze and shoot back to where you pressed R so if u are in the middle of a penta WHICH happened to me instead of going to where u were 4 seconds ago POOF your back in the team fight with four to five enemies ready to beat the hp out of you.....please riot look into this and fix my fav champ in the game please. this really messes with his game play P.S thank you for taking the time to read this have a good day
