If you are desperate you can C+D it. He's invincible so you can't actually shoot him, but the shield will absorb the hit. He comes from behind faster than from the front, so I wait a moment and super jump. He'll roll under you if he came from the back; if he comes from ahead I just dash forward.

You can get a couple of reps (3~4 I think) with Mudoon from: CD~C > 236236D > 66 > 214D > 5AA > 236A~D > Trap Hits > 2[C] > 5B > 5C > [236B~D]xn. Pretty sure I've done 4 off of that.

Yeah I have a lot of problems with j.A as well, it eats up every trap on the screen for free it seems. C traps at top of jump height sometimes work. It does seem that he can jump in for free; choosing to hit j.A or J.D mixes up his timing enough that F.Action doesn't work well at all. I usually end up just rolling out of j.A pressure. His 5AA has such huge range too.
