No way. SCV had way worse balance, worse movement, no lethal hits, metered GI, and just guard got kind of silly at high levels. You're also not making a good point about movesets, because the typical sc6 character still has more moves that are actually USEFUL, since movesets are better balanced. Fuck, just look at mitsu in scv. Incredibly braindead. Now look at the mitsu we saw in evo WF. Fantastic footsies and a really interesting neutral game with lots of tools being used.
And I feel you about setsuka, but there's a pretty good chance she'll be added to sc6, whereas my favorite styles (talim and mina) never made it into scv at all
