here's some tips:
If you connect a J4 in the corner go for F12 into chemical toss or Kano Ball (Kano Balls doesn't give you an advantage which sucks but you gotta do what you gotta do). I noticed to did J2 a lot but it's hard to convert anything from that because of the gravity.
On a punish, like when the Kabal nomad dash out of nowhere, you can 11 into Kano Ball or Chemical burn.
Also, I do this do, but walk up grab on knockdown is risky against good players you can bait it and back up or fake a short hop that works well.
But good shit! I only play Ratbag now but I kinda wanna go back to dirtbag for a bit.
