Lol, its funny when clueless randoms try to mention skill sender, you can clearly see the skills are being pressed throughout the first row within the first 20 seconds lmao, I didn't watch full vid but that's obvious already. If you can't tell if a skill is being pressed, heres a tip, skill icons don't randomly flicker when skill sending, they're not even affected by skill sender other than to display the cooldown.
Tl;dr stop being a clueless moron spouting out bullshit when you don't even know what a skill sender is or does.
OT, nice video, ***ing demisse destroyed loser lawl.
