To those saying Ragna is weak: I dunno about that, according to Fluck, Souji in NEC said he was still strong. Most japanese Ragna players in vids seem to be mostly weak players (people we never heard of before, so we have no idea how good they are as player, and to me they seem to be doing inefficient combos and shit), and the notable ones I've seen like HARA, potofu, Naru and Kaqn seem to be doing well so far. We need to see the likes of Sakomoto Ryouma playing Ragna to see his true potential as a character.
Edit: Does 5D(1) > DS not work anymore, at least in the corner? Also, does it work midscreen? In the corner, I hardly see players go for it, instead they always do 3C > 22C> DS.
