I can't begin to explain who stupid the first section of that comment is. Every class takes the same time to grind out and benefits a different play style. Hunters aren't any easier to use than warlocks or Titans. The time it takes to grind is no indication of skill required or ease of use. In terms of actual usage, the hunters where merely better pvp choices. This lead to skilled players maiming hunters, which can in turn cause the belief that it it completely supirior. I also believe it's easier to play as the striker due to there fist of panic.
