Part of the reason I went to Claudio was for consistency there actually lol. B+4,2 would block punish and running 2 would whiff punish every time. With Josie I was doing f+1+2 and it kept whiffing when I should have been doing u/f+3+4. Asuka definitely has some wonkey moves which you should punish right.
With Claudio, I think f,f+2, 1+2 should probably work as a punisher. I haven't tested though.
