Okay, I looked at your squad and I would encourage you to check out www.swgoh.gg for some guidance on Mods.
You can look up each character and see what mod sets other players use most, including the Primary traits they use also. For even one character this can make a big difference in how they perform, across a whole squad it can be a huge difference.
As an example, you have six Tenacity mods on General Kenobi, while many other use six Health mods and that's before you even look at the Primary stats on each mod.
Bottom line, all of your squad need to be faster, and most probably need to swap some mods. Along the way, swapping mods, hopefully you can pick up some speed especially 3PO, Shaak Ti, and Padme.
It is a challenge to be sure, good luck and enjoy your win when you get it.
