I didn’t say that: it’s a repositioning ability like reaper’s. I don’t understand what the problem is with it being a skill where you can’t hack it, even considering venture has a casting time to go in the earth.
If you are going with that then we can say the same for having emp protection while underground. It only works underground, you just dont understand it yet
Double jump is basically just ninja skills (you can handwave it like with Hanzo). As for the rest, as an example, it could have been an early version of the Hardlight tech designed by Vishkarr. Given that they had to keep it quiet it would make sense to do the early experiments on a criminal organization (Shimada) which explains the dragons. As for why Kiriko has it, you could say that Kiriko’s grandmother went to the Shimada as a request (remember Kiriko’s Mom trained Hanzo and Genji) and had the power given to her granddaughter without her knowledge. This explains why seemingly nobody else has ever seen or used the fox spirit prior to the point where her mother is shocked that it is real when you would think she would have seen her mother using it at least once if the fox was actually real.
Something that could easily be used to hand wave away the magic elements, as Blizzard has said magic does not exist in Overwatch, as it does function very similarly to Vishkarr Hardlight tech.
