Galactic War Battles (unbalanced)

GW rewards a broad roster, so the best thing to do is to gear up more toons and build at least three strong teams. You should be preloading these teams with TM in the first five nodes, and then work your way through the rest carefully, but be willing to sacrifice toons or teams to make it through nodes 6, 9, 11, and 12.Those nodes are always harder than any team you have on your roster (until you break node 12). That's true for everyone. If you are getting bad RNG to start, shuffle your team members around some, swap in other toons. That shifts the RNG seed and makes the opponent behave differently, but you also might end up finding a weakness. GW is designed to make you fight teams stronger than your own teams. Keep trying. GW goes through unbeatable phases for everyone. Keep playing and trying, and as your roster broadens it will get easier.
