I would counter by saying Hunters only seem like the easiest because they are the least gear dependent, meaning they do very good damage, with lower level gear. So even a bad player with low gear can do decent damage facerolling their shots. The counter side to that is that they don't scale as well to very high level gear. Regarding PVP, hunters take a decent amount of skill to play well when they've got a melee tagging their butt.
