Excited to say that I am done with finals and can finally focus more on Rivals!
I live in the NY/NJ area with good opportunities to visit strong Melee, PM and Smash 4 events with some top players in those games. In the next few weeks I'll definitely be able to bring out Rivals to show it off to players and get some buzz going as well as get feedback from a variety of players. If possible, I'll look into possibly recording it all locally or perhaps streaming it (anything that would cause slowdown is obviously out of the question, and if my streaming impacts the venue's streaming obviously they will get priority). I also have so really cool ideas for ways to teach people about the game who have never seen it before, and anything I create I'll share here so that other people can use it as well.
Regarding the game and the current discussion of mirror matches. Smash Bros has set this precedent before, because all enemies can use Peach turnips, Link bombs, etc. if they catch them. Also, a Wario can steal another Wario's bike, a DDD can throw another DDD's Waddle Dees and Doos, a Villager can chop another Villager's tree. Those are all Brawl/Sm4sh examples, but I think it makes sense. I think it makes those characters' matchups more unique because the things that you used to use to beat other characters can now be used against you, you have to be more careful with it because the opponent knows. I like that it makes those matches different and I see no problem with it.
To be honest, if letting a Wrastor use an enemy's windstream doesn't detract from the matchup (by making it too easy to excape combos or something) then I think that should happen too. If it doesn't it's no big deal, but I think that allowing mirror matches to work that way adds depth.
