Regarding the "Celestia is an idiot" entry under Twilight's Kingdom - while 'what the buck was she thinking?!?' is an entirely valid point for discussion, I don't think we can say things like 'It goes without saying that attacking Tirek four alicorns-on-one would have worked' unless the show or the writers actually do say that. If its just a fan theory, none of us can speak with absolute authority. Plus, it actually doesn't go without saying; even wielding the combined power of all four alicorns Twilight couldn't actually do any lasting damage to Tirek, and that's with the power all focused into one giant beam instead of four separate lesser attacks all going simultaneously vs. his damage soak.
