Contrary to the official announcement, mob difficulties have not been fixed. At least from where I'm at (VR7). The most gloriest example had me fighting 4 mobs for a simple quest complete.
3 mobs had 8,500 hp........the named, but non-boss had 16,200. All of them hit me like a truck. The non-boss even swated away an OC dk standard (500%) and didn't flinch.
Add this to the perpetual and unsolved issues: MAC ppl come to mind.
Place the fact that you have a major 3-day weekend in the US........and I can't come to any conclusion other than if you're having problems with anything...you're hosed.
I expected better.
