Not trying to sound like a jerk, but I think someone else mentioned Dragon Pulse over Ice Beam back in the day on Milotic. It's just that a lot of people pair Milotic with *Insert OU Dragon Here* and seeing as they already have an attacking Dragon move, it was more logical to give Milotic Ice Beam.
