Hello, Seiiki here!
This is just a test recording and a small showcase of Dual Blade's moveset in Mabinogi Heroes China. The first vertical spin is the XE only move that you can use when clicking L+R together at the cost of HP (Which is a horrible condition and I almost always kill myself when I accidentally do it).
Anyway, it looks like you can wait a long period of time while combo-cancelling before you continue the combo as long as it's right after a dodge.
After playing a little bit, these weapons feel "heavier" than Twin Swords, and the player-skillcap for them seem to be much higher, too. Back when I previewed Twin Swords in MH China, they didn't feel as hard to play with as these babes.
There's a certain perk that frustrated me while playing Dual Blades and that's when you press a directional key and click the smash button you'll do the hook move (you can see I messed up and did it in the video). I certainly hope I can get over this perk when it finally hits NA later this year. Or else I'm gonna be killing myself because I accidentally hooked on something...
Well, this is all I could record since my computer ain't the best thing to record with! Let's hope Dual Blades hit Vindictus NA sooner than July!
