No, I think Idol Defense is fine. You will need the defense Idol Defense can provide when facing up against rush decks such as Hanayo Ni Kai or Midoriko Three-stop. Even at 5 ener, it will be relatively simple to play Idol Defense because you are getting rushed down and therefore have a lot of ener. Against other decks, you can usually play Idol Defense at 5 ener because Anne actually accumulates ener quite well.

Personally I think Idol Defense is perfectly playable in Anne, as long as you are not running Big Bang.
