Newsflash my friend, archetypes were trivialized when they started proliferating powersets with Issue 12.
Tankers / Scrappers / Brutes to the casual player are so interchangeable that now the majority of players lean toward brutes (those of us who are aware of the minutae of each archetype recognize the subtle differences in each archetype).
Defenders / Corrs to the casual player are essentially the same, aside from swapping primary / secondary sets.
Dominators are just Controller primary / Blaster secondary.
MMs are a bit more 'special' with the pets primary, but still have def/troller secondary abilities.
Sentinels are just blaster primary / melee secondary.
I'd much rather go back to the times where powersets were locked down to specific archetypes and you ultimately had to pick that Tanker to get Ice Melee / Ice Armor or Spines for scrappers, etc.
Not trying to burst bubbles but Incarnate powers have done little to trivialize archetypes compared to powerset proliferation.
