I agree. It is completely hopeless. If you have 6 people in a raid it is pretty much gg because 99.9% they go in with Aggron and Draco Meteor Dragonites.
I saw a togetic raid a week ago with people using shit like Registeel and Lairon along with Aggron or Unpowered up Mewtwos. There were 5 people and if not for me they would not had been got away with it.
