I'm going to have to disagree with you here.
there's nothing saying enemies in this game have to follow specific archetypes. Even from level 1, when you're fighting Hellions, can you say what archetype any of them are? (hint, they don't have one)
Plenty of powers are auto-hit... Caltrops, Flash arrow, Disruption Arrow, any debuff toggle, non-damaging tank auras, heck, I'm pretty sure Oil Slick Arrow is Auto-hit
Status effects for non Armor based classes can be annoying, yes, but they also provide some sort of challenge to the game. There are multiple ways to combat Status effects, however, and they should be used. If you remove any challenge from the game is it really a game anymore?
see #3, all player debuff toggles are auto-hit, all tanker toggles that don't do damage are auto-hit.
