so I've started ending combos in 2C more and created this:
X>2C>282A>oki options
barrier>airdash j.B>j.C (Overhead or catches backdash)
barrier>airdash j.623C (Catches upbacking)
Delay barrier>j.D (Overhead, doesnt combo on non-counter but will bait DPs)
barrier>falling j.A (Safejump)
barrier>2A (Catches rolls/quicktech or just used as a low)
Use 292 instead and j.4B for crossover works too.
272 into poison nail can catch some things if you just need a safe poke to win.
