Talon is supposed to automatically autoattack his target after he uses Q on them. However, pressing it twice cancels that autoattack. This is a very annoying bug that leads to a lot of missed kills.

I will post this bug every patch until Riot fixes it, this is thread #2.

HungryAngry2SPP2 votesOK repost it, but not daily. Once a week should be ok for 2 reason:
TH3RM4L4 votesI said every patch, which means once two weeks. It would be meaningless to post it more often than that.
HungryAngry2SPP1 votesSorry. Didn't notice the "every patch"
Ðu Šhiedah 1 votesI died cuz of this bug i W and Q on zed but it didn't basic for the passive -.-
Slam Dùnk1 votesi feel like most people are glad its bugged cause right now everyone hates assasins good luck gaining traction you should get help from talon mains discord
HungryAngry2SPP1 votesJust for curiosity, where did you read he should auto AA after melee Q.
TH3RM4L1 votesI don't have to read it anywhere. Talon always autoattacked his target after melee Q, but for some reason it doesn't work anymore if you click Q more than once.
