I'm on the verge of quitting the game. Because of the anticipation of OG Chewbacca being required to unlock Jedi Luke, I spent a few hundred dollars to bring several of my bounty hunters to g12 and so forth. And even after spending that money, I barely noticed a difference in my characters gear levels when going after 7* Chewbacca. I did not have Bossk, or any of the recent bounty hunter additions at 7 stars. But I had Boba (g12.5), Dengar (g12), Zam (g11), IG-88 (g10), and Greedo (g9). Before the event, all of my bounty hunters were at g8. And what's surprising is that even after increasing my bounty hunters' gear levels so significantly, literally hundreds of dollars worth of gear, the 7* Chewbacca event was still damn near-impossible. I put in hundreds of tries, watched the cutscene over and over again. I had to watch ROLO ability block 3/5 toons and see Dengar not get hit with a crit, leading to R2 getting smoke screen off. I moved millions of credits of mods worth on my bounty hunters. Trying arena speed sets, potency sets, and even a combination of both. After having gone through all of that (and more), it's hard to enjoy this game as much. I take responsibility for my own investments, and if there are no rewards after said investment, best to stop investing.
Only thing that will stop me from quitting is a public announcement made by CG, acknowledging the overwhelming negative feedback that this event has gotten. Then stating that the event will return again before Jedi Luke's Hero's Journey drops (as R2D2 with CLS & BB8 with JTR) with also a more reasonable gear requirement expectation.
**Edit: I started playing this game back in November 2015, but took a break from December 2015 - August 2016. I've nearly reached 3m GP (certainly possible to reach if I spent the time to equip all my mods). I am by no means a new player who just wants legendary characters to be given out like candy... I like difficulty, but watching Han crit 35k+ on bounty hunters like Zam, whose rework didn't even include a health or protection increase, is just insane. Considering that it took ep4 characters to unlock CLS (Bespin Luke), we just know that it's going to take ep5 characters for Jedi Luke. The whole Chewie event was basically a nod toward that end, with Chewie being a requirement for that hero's journey. I spent so much time and money investing into my rebels and any potential requirement for Jedi Luke. I 7*'d and g12'd Hoda before even touching Wampa. This event is one of the grossest slaps in the face. No matter what, whales should be able to complete any event (not raids...) with 100% ease, non-RNG dependent. They paid for that right. They are carrying the development of this game for all the free to play players. Completion of legendary events should not be dependent on which characters from a faction you bring in with you. If you have five members of that faction at 7 stars, then you can enter tier 7. If you got them to around g10-11 at lv85 with omegas/zetas, you should be guaranteed completion. This is not unreasonable at all. Considering the gear and skill mats required to reach those leveled, and how many different factions you would need to get to that level, that is enough of a barrier to prevent a majority of people having unlocked legendary characters like candy...
My final send off here is that I just want to take a moment to laugh at the guy in this thread who's boasting about having "skill" over whales just because they managed to get lucky enough to 7* Chewbacca. Let me just say that being able to 7* Chewbacca at lower gear levels in comparison to whale players is but a testament to the fact that this game has evolved into a state of entropy, becoming heavily RNG dependent and requiring hundreds of restarts to even see a glimmer of chance.
