rip Kellth, trying to give a little bit of honest help without a full enough understanding of the subject at hand.
So Kellth, it's awesome that you took the initiative and made a video to help people who might be in a slump or just making the jump from pub to pug. However, you're getting made fun of because counter jumping in MGE is counter intuitive in the sense that it doesn't help you learn to aim(it teaches you how to do damage without having to aim). Also, because your mechanics appear to be pretty subpar in this video it's (unfortunately) hard to take the video seriously.
I'm not trying to be a dick or anything, just letting you know what's going on in your thread. Anyway, hopefully you don't get discouraged and continue to make videos. You seem confident enough on the mic and everybody starts somehwere, so keep it up!
