'The enrage timer for The Dread Guard has been increased by 30 seconds in Hard and Nightmare Modes.'
This speaks poorly to Bioware's intent to provide challenging content, in my opinion.
Will future content be continually nerfed to the point of Nightmare mode being 'everyone and their mother can clear it in a day-mode'?
Where are these notes you're quoting here? I am unable to find any patch notes saying this is happening?
