D2 is pretty good, its not great but its all he has got next to dash back, and bat swarm, although I think batman can be hit directly on the head from right above.
The d2 is good because even if you get hit, most of the time it trades.
After D2 you can just about get a jump 2, and if you preempt the jump, you can meter a DB2 ex rang, B3, J2, 213, B23
