I used to main the Kensa 52 Gal, but I stopped because I need to be able to dodge easily. I'm always the fastest, no one can touch me at full speed. My hand-eye coordination allows me to easily evade attacks, along with being able to quickly scope out a weapon's weak points and strong points so I can counter them.
For example, if I'm up against a tri-slosher, I have no time to think. I dodge around to buy me some time, then I scope out the weak point (the side shots are very ineffective) and use that to my advantage. I side-dodge and splat them from behind, because you can only turn so fast.
For your Carbon Roller, the weak spot is it has a 2-hit kill for rolling. I know I can survive facing you head-on. If you use the vertical swing, I know to dodge to the side then splat you head-on.
I use the Dapple Dualies for the amazing speed and mobility. Any slow weapon (Dynamo Roller, 96 Gal, Tenta Brella) I am TRASH at.
Dapple dualies only have one weakness: The split-second gap between dodges. If you learn to use that to your advantage, you can take me down. But I'm NO easy opponent. Just saying, when I go full Japanese sweat, you're dead.
