It is frustrating but if you watch guides and youtube videos on the event, you should have known what to expect. I had g12 boba and dengar, g11 cad bane and ig88, and g10 greedo. I found what helped was getting dengar and greedo speeds over 200 so that after the initial moves, they go right after boba. I found with greedo's crits were key. Ended up getting lucky after 15 hours of on again, off again attempts as I used greedo's special for crit chance increase and then dengar's basic which caused greedo to assist and crit 7 times in a row to kill chewie. If you want to use the minimum and not involve bossk and jango, you shouldn't be surprised it's much harder and that you want to go crazy lol
