You need to get mods that makes you faster. Seems like you still got no +30 speed arrows.

I am quite sure I had some with lvl 72? Well at least you need them on STH and/or Biggs and Boba.
Even an e-type will do, just have the speed primary.
If your Boba goes first and can ability block many opponents, that would be a nice start. STH first is also good if he gives the others turnmeter, so the key is to be faster. If your Biggs goes first, you will be the one who instakills Wedge/Lando, not vice versa.
Edit:
The triangle mod on your Lando is wrong there.
(+11.75% Defense)
Give him the one GS has.
+31.5% Critical Damage
And the defense triangle from Lando goes to STH.
Also your crosses are bad.
But the protection cross from RG to Wedge.
But the protection cross from Boba to Biggs.
But the potency cross from GS to Boba.
Also your Databusses are bad.
Put the Protection circle from Wedge to STH. (the crit chance hurts a bit but you need the speed and prot.)
Get more of these protection mods :)
Also move your speed square from Wedge to STH.
Why does your JC get a 5-dot processor and your Lando gets a 1-dot?
