Shooting for 7* Chewbacca & 5* Falcon, any advice?

Slippyfist

My Bossk is 80/100 and G11+5. I have the last piece ready to take him to G12 as soon as I get to 7*s. I'll be doing 2-3 refreshes on his node/day until he's done, so hopefully another week or so? I still have Greedo in as my 5th ATM, but I also have Jango 7* G8, so I may end up swapping them.

Related to the Falcon event: Once I finish Bossk I'll be refreshing the Xanadu Blood and IG-2000 nodes to get them to 5*s.

Here are my BH Ships so far:



Also, I have been working in IG-88 and have him at lvl1/g1/4*s. How high do I need to level, gear and star IG-88? I'd rather not waste too much on him since I'm only farming him for the Falcon event.



Any suggestions would be greatly appreciated!
