Nerf or remove yi PLEASE RIOT!!!!

ok here is the deal yi is the most broken ass back champion in this game....i have watched challenger friends COMPLAIN seriously COMPLAIN about how broken he is and wish he never existed. i was in a game with a friend name Neogreg who was in plat last season and was dropped into gold from D1 to g5 due to every single game he had in solo/duo was against a yi jungler and was able to 1 SHOT him when he was playing as volibear, vi, olaf, jarvan IV, and most of the tank junglers when he was going fed by 8 1 or such what ever... i watched him in a game against a bronze player yi BRONZE FFS 20 0 in the game against 1 bronze player and 4 DIAMOND PLAYERS.... seriously i watch tryndamere 1 shot with warmogs,ninja tabi,sunfire cape,Randuins Omen, frozen heart, and thornmails get 1 shot by a yi with full build who popped ulti,yomu,and then alpha strike on him and i watched his health go from what ever it was at full health to ZERO please riot for gods sake change this champions ulti and alpha strike.

make it possible where we can see yi doing alpha strike in the motion so we can stun him or change out his ulti with just speed and stuff cause this is getting redic

he needs to be redone completely cause back when yi was out in season 2 and 3 he was fine but then you changed him complete and now everyone i know isntantly leaves games cause if they see a yi they dont want to feed him... YI TAKES NO SKILL ABSOLUTELY AT ALL PLEASE CHANGE HIS ABILITY COOLDOWNS OR SOMETHING!!!!
