There I was, having just completed the Epic Instance: Retake Weathertop, when I decided to enter Minas Eriol and have a discussion with Nishruk.
Well, while taking back Weathertop, I felt somewhat invincible, whacking 3 (on-level) Orcs at once, and suffering not more than a few scratches, but these Orcs seemed a bit different.
They did not quake-in-their-Orc-boots. Far from it. The first one (by himself) sent me to the Rez circle and no mistake.

When you are in an Epic Instance, the Difficulty aspect is turned off. Not so when you encounter Orcs in the Landscape. Especially Elite ones.

I have to remember this every time. If I forget about it, it leads to misfortune.

Fun!

I have a suggestion for the Devs:
You seem to have overdone it when it comes to relaxing the difficulty for that Instance.
Easy is one thing. This is way beyond easy.
Please revisit this Instance to at least give the Orcs a chance.
There are others that are also perhaps a little on the "too easy" side, but this one is beyond the pale.
