So how about them new dungeons? (Layout and difficulty)

Enemies may have different HP Bars, though it still doesn't change the way you go about things. I can give one mob the hp of titan ex. It won't be harder, it'd just take even longer.

It's not all about hit points. As gear scales damage does of course but so does healing, damage mitigation and all of that nerfs an encounter quite hard.
