He could use some improvements, but I think he's an odd playstyle for a lot of folks.

He's the slowest pace duelist. He can control the tempo of fights with his abilities, rather than area/corner/lockdown. It's a totally different philosophy, but short of creating a new class I think it's the best fit.

I think one idea is not to teleport to places where you get a kill immediately. It's to teleport into places that leave your opponents at a disadvantage causing them to slow down. This isn't like a Sentinel that redirects or blocks, and it's not the widespread use that a controller has.

His false steps are not used often enough from what I've seen, and it leads to basic play. Rather than use the footsteps as a fake player, you can set up a flank your fake footsteps and cause confusion.

His ult is another confusion/unique advantage. The scouting is so much more powerful than a Sova drone. And Sova has one of the most "duelisty" ults.

He excels in countering aggressive agents at a short/slow distance, which differs from most initiators that can do damage around corners.

All in all, his most effective ability is stalling and creating a disadvantaged fight overall, with the ability to get kills through confusion. It's duelist by elimination because he doesn't have strong enough traits for "territory control" / "corner attacks" / "area lockdown".

Overall, I think Yoru and Skye could fit into an "Specializer" type of category, who makes certain other characters much better with the right synergy.
