On the note for ninjas, the importance of Ninja is not in rotation, but utilizing whats available to you and becomes an issue of priority (In most cases). If your GCD's are not being used when they are available, that's a dps loss. If you aren't using Ninjitsus when they are off cool down, that's a dps loss. Not getting Backstab bonus for Trick attack? DPS loss.

That also doesn't cover, clipping your own dots, or having another ninja DE over yours or the other way around, which includes Warriors Storm's Eye.
