Caught one of the times my Tidal Wave went the opposite direction!
Not often, but every once in a great while my R - Tidal Wave will seem to go in the exact opposite direction as where I aimed it. Since I'm not Karthus, this fucking sucks XD This time I nabbed a recording to present in the form of a gif and images.
The only thing I know that I did was I was using smartcast, I held the button to see the indicator, cancelled it then cast it immediately. I started issuing move commands the other way, but Nami's facing appears to have been in the direction it went as soon as it started casting rather than changing when I issued my move command.
