I got 7* chewie, but I absolutely hated the event. I thought this was the first legendary I prepped for to be ready to 7* the first go around...hoarded crystals and gear so I had zBossk at g12, Boba at g12, IG and Zam at g11, Greedo at g9 and g8 Cad...by the end of the week I farmed Zam to g12 Greedo to g11 and Cad to g9, and every restart was just a horrible waste of time. I read all the advice columns on modding, kill order, exactly what rng I needed to play out and it took hours upon hours for those events to unfold...
This was the legendary event equivalent of the sith raid and we all know how frustrating that abomination has been for the 8 months before the devs adjusted that rng (and admitted that constantly restarting a battle to get favorable rng is a bad gaming experience).
I think this is a horrible precedent for legendary events...you've already milked us for everything after 9 straight months of marquee only events and single hard node farms and further compounded the angst by dragging your feet on updating raid rewards which weren't even fixed until after the chewbacca event went live.
I completed the event and feel like I never want to play SWGoH again...
