Can Divers be Healthy?
It's really somewhat of a simple question. Riot's categorization includes "Divers", champions who throw themselves in the middle of the enemy team with the intent to kill and being a legitimate damage threat. This is different from Vanguards, offensive tanks who specialize in initiation and unloading CC while absorbing the damage brought down on them in response.
My concern however is whether or not the role of Divers is healthy on a conceptual level. Divers include Xin Zhao, Vi, Diana, Aatrox, and Rengar; all of these champions share a common problem, and expose a problem with the Diver class as a whole. And that problem is that many Divers are feast or famine: They either get fed and make themselves an absolute terror with sure-fire ways to get in and the damage and durability to almost assuredly get a kill, or they fall behind and their only means of contribution is still launching themselves at the enemy team and likely dying. That's doesn't come across as good gameplay health, in my opinion.
The problem arises in that Divers aren't Vanguards or Assassins; they aren't meant to be a damage-soaking CC threat, and they don't have means of quickly getting out if things go south. So that's what brings my question to front and center: is it possible for the Diver sub-class to be healthy period?
