When I pressed E manytimes at the moment, 
Azir costed mana 2 times (didn't cost 120mana at once. Azir used 60mana, then used 60mana again.)
I think Azir can use "Shifting Sand" while moving with "Shifting Sand", even though it is on the CoolDown.
RiotRiot Exgeniar2 votesedit- nevermind, I figured it out. If you are spamming E during the cast time of W, and you are casting E within 0.07 seconds of W finishing, it would cost twice the mana. My bad I made a mistake on the spell-buffering on Azir's W. You can just E once, Azir will buffering the whole combo for you during the W cast time. You can just WQE and it will do all of it for you.
Sahn Uzal1 votesLooks like you have some time to spend on Azir bug fixes... lol I have to learn Unity for a school project, and for godsake, I respect people who can actually code that stuff...
I don't even wanna know how much work Azir must've been considering the struggles I had making my cube move when I press arrow keys, LOL
RiotRiot Exgeniar2 votesit took like 30 minutes :\
Wasn't too bad, found a lot of other tiny issues while fixing this bug though. He's complicated. 
iamthegoatofwar1 votesyou mind letting the player behavior guys know that people are randomly getting perma-banned for 3rd party apps? there's enough posts lately that you guys should already have a response.
Alaragi1 votesBasically I don't press a lot for the combo... However, my ping often be higher than 200 pings, so ocasionally I have to press several times to do the combo smoothly. Anyway, if this bug were unfixable, I will care not to press E too much. Thanks for the comment.
RiotRiot Exgeniar2 votesNo seriously. Just Press W then E (once), and it will process and do the combo for you. This excludes the fact that the packet / instruction is lost during transit.
