I'm a newer player about to be at lvl 85, would like to have chewie and c3po when they come around. Provided they were geared appropriately could ewok scout, teebo, logray, Paploo and chirps get the job done for c3po? I've seen a lot of different combos people saying they did it with this or that and since I already have teebo and scout at 4 star, I'm looking to maximize on having them already while only farming the other 3? Any help or opinion would be appreciated.
If you only replace one of them, probably Scout - Teebo gets hated on a lot, but his turnmeter removal is valuable.
Also, Logray is a looooonnnnnng farm, as he's guild store only (unless you get lucky with the Forest Moon event) and has a habit of not showing up for days at a time. I'd start making sure you always have at least 900 guild coins in reserve.
The bonus tier of Endor Escalation (The AT-ST battle) requires a 7* Wicket, and awards 2-4 zeta mats. It usually comes around once a month.
With appropriate gear you can do anything--it's just that "appropriate" is a floating scale that varies based on which characters you're using. For example, the amount of gear needed to get C3P-0 with Ewok Scout will be higher than the gear needed with Ewok Elder. Every character you use will lessen that gear threshold. The optimal team will be Chirpa with a zeta, Logray, Paploo, Elder, and then either Wicket or Teebo, but preferably Wicket. The strategy of the event is to keep your Elder alive as long as possible through a combination of Paploo's taunt and Teebo or Wicket's stealth so that the Elder can res dead Ewoks (and, with Chirpa zeta'd, will call attacks when doing so). The thing people don't like to talk about when it comes to Ewoks is that they're actually quite good. They're not meta, they won't get top tier rewards every day, but they're a solid team that's great on offense or defense in territory wars and grand arena. So, honestly, I recommend continuing to farm them even after you get C3P-0.
As for Chewbacca, there are a lot of bounty hunters to choose from, and, like Ewoks, bounty hunters are a really solid team so I recommend continuing to farm them afterwards. Good ships, too. People don't mind gearing up bounty hunters, though, because they're also useful for several recurring events. Bossk is an all-star, Boba's an all-star, Dengar's going to really make the Chewbacca fight easier, and since he does that with thermal detonators you may as well go with Greedo and Zam. Gives you a nice little team right there.
