I was thinking. Kylo Ren looks a lot like Darth Revan. Perhaps, in-universe, Kylo dressed like that to pay homage to Revan; and that's why the story group hasn't given a definitive answer as to if Star Wars: The Old Republic is canon or not. What does everyone else think?
Looking like someone doesn't mean it's that particular person someone is imitating or pay homage to, plus just because Revan would be mentioned, doesn't mean that it would be that Revan. The guy might have the same name, it doesn't mean that Kotor/TOR Revan is that Revan, they just share the name.
Also I'm pretty sure TOR is under Legends like everything else, it's not canon but that doesn't mean it can't be drawn from as support.
