heres a nice bug in the ja+ mod (almost every server is running this mod so you will have it easy to find one)
with this trick you can do every move/specialmove with every saber without losing force by pressing only one button...
when youre on the server turn your saber on, then open the console and type:
/debugsetsabermove *
*= 1-100
the special moves are in the range from 20 up to 25 and from 50 up to 55
to bind the moves type:
/bind q debugsetsabermove 50 (q is the button where its been binded)
