I lack a four star yellow troop (obviously I have each flavor of three star yellow troop). Should I continue to wait or go ahead and level one (or more) of the existing troops? I have saved my feeders for a long time, so I would likely be able to level the troop pretty far.
My normal yellow stack is Onatel, Leo, and Danzaburo / Li Xiu. All maxed, no emblems. I don’t really feel I’m struggling when I fight purple tanks (though my performance against purple titans is appalling), so it isn’t clear to me how much I’d gain from a better three star troop.
