actually the bug about the jin is very useful especially on a one on one bout.
it is useful since the chammagon throw could actually provide a stun and since you'll use skills immediately,the stun would be a very good disable and will provide a very good chance for your skill to hit the enemy.
just a tip:
just use the bug when you have two bars of mp..
stun with the chammagon throw and then use second skill and then do an aerial grab.
i always do this and it helps me to win the game.
