it's probably not a good time to say this considering 1.2 is coming close, and someone probably already mentioned this
but out of all characters, lloyd has something unique, no one else in the roster has it so far
holding down while on a platform causes him to just suddenly drop down, it's not that large of a problem (unless the stages you're playing on has platforms outside the stage) but the fact that he's the only one who has this is annoying
also it seems like there's an extra hitbox for rising/diving falcon that looks like it's supposed to connect with the final hitbox (which is the pull attack), it never does it properly and just gives a large opening.

i assume you're talking about his grounded DownB before he dives, you can hold the special input so he rises somewhat higher before diving (or release earlier so he goes lower), just did some testing it and it seems to have a set knockback (as in, even at 999% it does the same knockback), so the timing mostly depends on a character's falling speed, floaties can still entirely avoid it with proper DI though (and jigglypuff is impossible to hit)

i was talking about the ending part, not the one where he jumps and dives, its a really small hitbox which appears seemingly at the very tip of the end of the dive, it's a bit hard to hit but it's there.
