(Gameplay) yasuo e at max causes him to auto attack first then dash

i play yas on 250 ping and he was fine till last patch i tried him in practice mode since 7.7 launch and his e at max rank is clunky even with items he auto first while u keep spamming e its like a built in auto attck in his e.I switched to Eu server with significantly less ping and its there aswell

1 take yas in practice mode

2 max his e with pd and tier 2 boots

1. 3 practice dash and u will notice he will preform an random auto attack before every dash

please tell me if i am doing anything wrong i tried on 2 different servers

i can give a gameplay demonstration of the bug if u done believe me
