Chewie Event: The most frustrating thing to exist.

I just got 5* chewie with boba g10,cad g10,greedo,zam, and dengar g9 and no zetas.
Teir 6 impossible with this team. Working on g11 boba, g10 dengar and zam. We'll see. Next time I'll have bossk zeta and ready so yes it's hard. My thoughts are this game is a grind all the time. Let's reward people for grinding toons to 7* and at least g10 or 11 and stop this madness of needing g12+
