As if it mattered? Facts still stand. Video evidence is video evidence. You can argue about the age of the "metagame",which I've always thought was ridiculous in the first place, but what matters is here, now.
And personally i don't think Diddy is all that bad. He's at least pushing an offensive almost all the time and he's fun to combo.
Well that's the problem here. You haven't provided any
Facts. All I've seen from your posts is conjecture, based on your personal experiences with the MU maybe, or videos you have watched- I don't know. The fact of the matter here is that coming into a thread and saying "this character is impossible to combo because reasons" without giving any actual proof or evidence of this claim, is not stating a fact. Period. In any situation.
You say you've seen videos of Rosalina doing nothing but being campy and defensive so therefore that is the basis of her character and anything else is what, a lie? So can I say that Captain Falcon is a campy character that does nothing but play keep away and fish for grabs because I've played against ones on For Glory that do that? Is that a fact now just because I said so?
There are tons of videos right HERE on this board showing plenty of different styles of Rosalina, including aggressive play. You say she can't be comboed because of Luma, but that's not true either because I main her, and guess what-
I've been comboed.
When Luma is attached to her (not in the sparkling state from Luma Shot) he actually goes helpless and flails around for a few moments while she's in Hitstun. All the better if you can hit with an attack that snags the two of them at the same time, because Luma is helpless after getting hit until it touches the ground.
There's a lot more that goes into figuring out the complete workings of a character than just a few videos of
One Person playing them in a tournament against a limited number of players of varying skill levels.
I still remember when people thought Robin was Top Tier because Nairo was winning all the 3DS tournaments. Now he's considered like B-tier or in some peoples opinions worse than that.
The real fact here is it's going to take a
lot more time to see where ANY of the characters
really stand in terms of their place on a tier list, or their overall dominance of the meta, etc, whatever.
If you don't agree with me, that's fine- but nothing you've said about Rosalina yet has been an absolute fact aside from the notion that she does force certain characters to have to adapt to a strategy outside of their normal play. -and personally I think that's a good thing. It freshens up Characters that would otherwise start to have stale matchups IMO.
