Can you strafe jump?
Using the damage for a massive speed boost can some times save your butt, it's a last ditch thing and is situational though.
I've had times when I'm jumping across something and their LG helps me get away and I ride on the beam and escape. Careful though because if done wrong a good player will juggle you and you're dead for sure.
Edit: also damage push seems to be highly underutilized. I've made impossible jumps by tricking people into shooting me with LG to send me across a really wide gap where they have no chance of following.
Damage push is also useful for denying opponents from jumping up to where you are or even knocking them off the map when they're flying over to the rail in Longest Yard for example.
