Also I really cant take credit for the B1,3,trait thing. I did not discover it. That information was given to me. I cant say where I got it right now, but it will be obvious in a few days.
Also these jump in 3 into B23 combos are much harder to do in the final build because the gravity seems to have changed slightly. (For instance 2,2,3,minigun the minigun now whiffs where as it connected in the vanilla build) You can still do the Jump in 3 into B23 but you have to do it very very deep. To deep to be considered a BnB I feel. Jump in 2 into B23 works fine. Also you can still Jump in 3 into 2,2,3 easy as well. The patch changes alot, so alot will probably have to be updated.
