it's 4am and i made an account solely to confirm that you're being an asshole, yeah.

let's look at the flow of conversation here. your first post is very clear on it being about genji. deign proceeded to answer about flick shots, which is the first and easiest answer. as far as they're concerned, that answered your entire question, so when you say "what about the first part?" without any context in the same sentence, it's pretty easy to assume "the first part" refers to the "first part" of the video of dva not getting hit by the high noon. they answered accordingly, and then you responded back very aggressively when they're just sincerely trying to help or explain.

as for an actual answer, i believe genji's dash works the same way as tracer's blink does (i am not 100% on this though), so when genji uses his dash, in mid-dash, he's actually considered to still be where his model was at the start of the dash, so that could be why mccree's gun looks like it's not aimed right. however, again, i am not entirely sure. it could just be that the actions happened so quickly that our eyes just can't really keep up, since to me it looks like a legit flick.
