You know, someone should do a run where they use moves opposite of their stats. For example, Mr. Mime is a Special Attacker but he's only allowed to use Physical Moves. Also, Attack for Crobat.
Special Crobat isn't walled by steel types thanks to heat wave. It also has other nice coverage moves exclusively on the special side. That's a nice trade off for less damage output. I'd choose special for those reasons alone.
