The last time you posted this type of thread in this section, I moved it. Please don't do this again. You should know now that these threads go in the in-game team help forum. However, since you already have a thread over there, I don't see the point in moving this there. Just edit your post in that thread and post in there again asking for help with your new dilemma. I think your team is fine and you don't need a legendary bird.
