I agree with you on the mitigation our armor has when it comes to physical dmg especially if we are carrying a shield, however all MDPS have a mechaninc that more or less renders armor almost useless SR will help with that alot, but we still will fail at getting any type of cast off while a mdps is on us. i know spriests and and boomies can make that same case, but their utility far exceeds ours when it comes to escaping from Mdps.
