User blog comment:Shigfugjum/A Display of Utility: What your Champs Can Actually Do/@comment-4814368-20140415234852

Good stuff, although I don't think I would personally expand the definition of utility as broad as you do. I think an important thing to note for players is utility diversity in team composition. If you want to include Ezreal as a champion with utility, then there are many other ranged ADCs who can also be included. The question is whether or not Ezreal adds a form of utility not covered by someone else. The way that Morgana or Gragas can reset and drastically change a team fight with their ultimates is significant and not easily replicable across the champion pool. For those looking for that extra utility, they might find it more useful.

That being said, if Ezreal provides something your team otherwise lacks then yes, considering whatever his kit provides utility wise, regardless of your definition, is important.
