The only thing worse than disappointing your teammates is making your opponents feel good about themselves. Laned as Malz against Akali, walked all over her for the first ten minutes or so, forcing her to b twice and only not killing her because she somehow had the prescience to use her smokescreen every time I was getting ready to blow her away. I was up by like 40cs, had her tower almost down, basically playing like she wasn't even there.
Then bullshit happened. After her second b she realized she was getting her ass kicked and decided to turn up the pressure, throwing her things and jumping at me and shit. I knew I had her though so I didn't b. Finally, the moment of truth hits and we both engage for real. I ult her, gg.
No wait, no I don't. I can't. I hit her with it and nothing happens, I click frantically and then I die. I get an oracle on my way back to seal the deal. This time it works, gg.
No wait, still doesn't. What the fuck was the deal with this Akali?! I click her and click her and nothing works. I died twice, to the queen of snowballing no less.
After that I got sick of her bullshit, circled around and hit her from behind, killing her finally, taking her tower, and going up to wreck top lane. Surrender at 20, gg.
Still, that was bullshit. I had her over a barrel and then stupid shit happened.
EDIT: Oh wait, I bet it's the skin. I was using Vizier Malzahar which looks cool and therefore makes you play worse.
