ok, here is a finisher if you accidentally throw out a 6A in the corner (didnt see anyone messing around with 6A combos so this one is the best I got. had to come up with something for when I throw it out on accident =p)
6A 623B RC 5C 6A 623B RC 5C 6D 6239B
someone needs to test out the last hit because i suck at that input and the opponent might be able to tech out, but if your opponent has bursted and you have 100 heat there is no way they will survive this as it does well over 5K to a bursted opponent. if they havent bursted chances are this will make them burst =]
If no one's found this yet, I call it rei-Taijutsu. note: I only tried this on jin but i expect it should work on all characters.
Also a little less useful but when using a throw against hakumen, tager, and ragna rather than doing throw, on hit j.623B, RC, airdash, j.D, 2B 6C j.B j.C you can rapid right after grabbing the opponent and use the stun time to do 2B 6C j.D ... w/e. does more damage this way but I bet this is old news.
Thats all I got for this post, if someone can try out the last hit in my 100% heat finisher that'd be helpful
