I'll sit down with Carl and try some stuff.
Note that 5A > anything can be interrupted.
Also 2A > anything. These can both be jump canceled.
5B > 6B can be IB'd and punished. But 5B is jump cancel-able, so watch out.
2B into anything is 100% guaranteed.
If you IB j.2C cross up you can punish.
3C can also be punished on IB.
If you IB 5C, you can punish it's recovery. Only complication I see is gear super on reaction.
5C > Gear doesn't gatling normally though, so I don't know who would do this unless they have you cornered.
