You mentioned Meta Knight's attacks have actual start-up now. However, what I want to know is do his tilts, smash attacks, and aerials still have laser priority? Laser priority is what it says on the tin, his attacks act like Falco's lasers and cannot be clanked/clashed and he cannot attack projectiles like Samus' missiles. Do you remember seeing MK ever clanking or clashing with any attacks? In Brawl, the only attacks that could clank were Tornado (that's what it allowed it to have the "priority" it had) and Drill Rush.
Speaking of the Tornado, you said it doesn't last as long and it doesn't rise anymore. What I want to know is, does it still do 22% despite dealing less hits? And, also, did anyone try (when you played as MK) to challenge the Tornado? If not then I guess you probably don't know if it has laser priority like his other attacks. I want to know because what Project M did to fix MK's tornado "priority" was by giving it laser priority, meaning characters could throw out hitboxes and at worst they would just trade with the tornado (taking only a couple of % but knocking MK out of the tornado).
You say that low% combos are possible, but low% combos existed to some degree in Brawl -- how low% are we talking? 20%? 50%? Sheik's Ftilt in Brawl, for example, could lock characters until 50% and then the characters would start to go into their tumble state (higher %age and all). Is the threshold 50% where things start to become harder to combo? Also, would you say that there's a chance to combo into a finisher at higher %s?
One other thing, did you notice if you could DI normally at low%s? In Brawl, you couldn't DI during the non-tumble state and that's what lead to things like DDD's chaingrab being a thing. Is DI'ing reimplemented into the non-tumble state or could you not notice while you were playing?
Oh and is there any shield drop lag like in Melee? Or, is the shield drop more like Brawl? What about shieldstun? Could you shieldgrab almost everything that hit your shield?
That's all I got right now. I imagine most of this will probably be better answered next week but I thought I'd try anyway (especially since more people are just asking you about colors...)
