I disagree that PK flash and PKT2 are nerfed. They don’t outright kill quite as early, but their new properties make them better overall imo. PK flash is notably faster, has a little more forward range, and no longer sends Ness into free fall, giving it far more utility as an edguard and juggle mixup. Even with the nerf, it’s kill power is still pretty absurd given how noncommital it is.
PKT2 doesn’t kill as early and also lost it’s side hitboxes that sent opponents away from Ness (and if it still has them, then I haven’t landed a single one in my 40+ hours put into the character), but the introduction of untechable knockback makes it kill so much more consistently offstage. Once your opponent is at 30-50%, any edgeguard has to be super on point or they’re super dead.
As for a grab range nerf, I honestly haven’t even noticed, assuming that’s true. Do you have a source for this?
I don’t think Ness really needs any big buffs right now. His movement and (warning: very subjective opinions incoming) recovery are better than ever, and with PKT being as busted as it is, Ness might actually stick around in high tier this time around.
