I linked this in another thread, an example where a level 29 mob outside RFK did same or more melee damage as 31 elites inside the dungeon.
The mere idea that generic elites were supposed to melee for more damage than generic non-elites was treated with howls of derision from this crowd. So good luck convincing them.
None of our discussion really matters. If a bug is happening with mitigation, the streamers in beta will provide feedback and find it (like they did with the Stoneskin buff not expiring).
