The general power scaling of characters is that SC2 >>> SC4 in terms of overall power.
Raphael in SC2 had a 6BBB series that would blow SC4's version out of the water.
His SCC cancel good, but truthfully not very raph-like.
His 3B was a ground hitting launcher that you could fish for hits, unlike in SC4 where you have to commit to stance or else you'll only do 20 damgae.
2K giving a crazy +6 frames on hit.
Not to mention he had working AEs.
So no, I don't think it's a wise thing to say people want SC2 raph in terms of power level (because its' relative to the game, not to the character).
It would be better if people who suggest so at least bring up mechanistic or even flavour points on why SC2 Raph is preferable. I'm not a fan of too many stances, as it seems needlessly complicated.
