This sort of covers what Ive discussed before, particularly all the crouching/shielding/small hitbox stuff. I was actually the first one to mention this to Larry but it was mostly in regards to pika.

when we had our discussion about Diddy's fair against ZSS this is sort of what I meant regarding crouching.
I think right now we have a meta that sort of revolves around short hop aerials as a carry over from Brawl, and greater usage of ground tools (as well as pivoting tools like perfect pivots, pivot tilts, etc.) will someday play a more important roll (reducing your hurtbox is particularly effective against a spacing diddy).
