Actually....
Irelia's Q resets if its a kill.... The only skill that resets is the Q and notice not the W E or R. This is no hack, its just some amateur mock up vid to have people believe such so they would "download" his virus or spyware. His irelia has high damage output which makes last hitting easier than ever, this is what makes Irelia a scary top laner if you zone the enemy out early game and farm well.
