If not longer.
When you press W for the attack speed and movement speed boost on Warwick, the first auto is always at normal speed. It practically defeats the purpose of the buff for the very first attack not to work right.
So a month or two ago, they 'buff' Warwick, but leave this bug in? I would rather have bug free then buffed champions, it's downright silly. In the reddit forum, in the game forum, in the tickets, many of us complain, but it is never addressed or fixed. It's basic, and easily observable.
Riot this IS unprofessional. Please please please fix mistakes before introducing new content over and over, it's insulting..
