The Shattered Sun greatsword (fantastic moveset) has a problem with the moveset. When your weight is normal or heavy, the rolling attack is a combo that begins with a thrust. When you are at light weight, the game seems to count the roll (quickstep) as a running start instead of a dodge, as the weapon uses it’s running attack instead of the dodge attack thrust combo. It would be amazing to be able to use the dodge’s thrust combo with quickstep.
I realize now that this actually applies to all weapons, dodge attack doesn’t work with quick step.
