Started Galactic War with Lumi, Barris, JC, Geo Soldier, and Royal Guard. Used to finish all the time, but that started coming to an end as I started fine tuning my arena team. After working on my arena for some time (Phasma, Dooku, QGJ, Kylo, Shoretrooper), getting them over L70, all Gear 8, and their abilities to level 7 decided to start working on other teams. Droid team was a little side project but not really a focus. Obviously Rebels were necessary for Palpatine so went after them. Same thing, Level 70s, gear 8, abilities to L7.
Galactic War got a bit easier, as I now had 3/4 legit teams to send in whenever I hit a tough node, but alas, it actually started to be very tough to finish the last 2 nodes.
I bought the Rogue One pack when I 1st started playing the game (Christmas time-ish?), but didn't really do much with it... Ever since I have been working on them I've noticed GW, while a challenge - is doable. I have a weak R1 team that can get through the 1st few nodes, a droid team that can take out a node or 2 (They still have full protection), a powerful Rebel team (7* Palpatine with it) that can get past the 9th and 10 node (again, they start with full protection), A great Heal team that starts with full protection and then my Arena team that has full protection for the last couple nodes.
Galactic War is all about a deep roster for me. There may be the element that I did not get my Arena team to gear 9's yet and losing ground every day unfortunately, but maybe I did not trigger the game to start throwing L85 Zeta teams at me yet either.
@Billcarson66 I'm in the same boat... plenty of training droids... but, Credit poor... time to start working on those Scoundrel. Darn, another Squad that needs attention. Wish I would have done a Scoundrel team 1st!
