White hit don't "happen"

Hello !

Ok so, here's my problem. I'm actually playing warrior on Onyxia and if i remember right, i used to have this problem on previous melee characters on other WoW servers.

So, when i'm auto-attacking, sometimes, white hits just don't "happen", i don't how to say it else. But actually they do happen... here's how it goes :

1) Me attacking normally, white hit > slam > white hit and so on...
2) At some point, no white hit coming (???)
3) Me going "dammit"
4) Two white hits coming in half a second

So as you can see, the missing white hit, is in fact, missing the bus and catching up later. But it's really annoying cause it crashes my rotation timing and energy.

It's not about not being close enough to hit cause it happens even on a leveling 1v1 motionless fight. I usually have a low latency around 20ms when i look at the little computer menu icon so i don't know where does it comes from. Gameplay error ? Server lag ? Lag from me ?

Help pls !

Thank you

Slam resets the swing timer, use it at the start of the swing timer rather than the end.

Ok so it's a gameplay issue. I'm not yet to the point of being really careful with my swing, don't even have Weakaura installed.

Glad it's just me and not a lag issue. Thx !
