I could definately see Diana becoming much stronger with a cooldown change. It would help her stick a lot more and would actually help her act in a more brusier-ish fashion.

However the reason for the high cooldown is literally the strength and potential of the ability. By comparison abilities like Anivia's W or Hecarim's W, they are very powerful spells on the level of ultimates that could be fight changing. A few champions have spells like that, Veigar's E has a high cooldown and is a game changer; the only reason Veigar's is lower than usual is because his kit is a bit too dependant on it so it was adjusted lower (and given more counterplay).
