I just tried to beat brutal and failed. I don´t have the best Patriots team, I would call it average but I did beat the first two stages with my heroes having 90%+ HP left and some even have Phalanx shield active. I fight good against Galante and then Dogface spawns, immediatly casts his skills and whipes out my whole team. That´s the most frustrating stuff I experienced in this game. If I get to the last stage of a raid and the last hero spawns with my heroes still having more then half of their HP I should be able to beat it.
What do you think about that? Should raids like this just be done with all five heroes beeing 8* Gold? Or should there be a chance to beat it if you just play well?
