Flush with my success soloing most of Carn Dum and Urugarth at 56, I strode into the Mirror Halls at 60 feeling like Babe Ruth in a game of T-ball. Sure, this would be on-level, and I was six levels higher than the Angmar instances, but now I've got EoB, some nice 2nd-Age weapons...

20 seconds into the fight with the two matrons, and I'm toast.

I gather Angmar instances are easier than Moria instances not only because of level, but because Moria is scaled for players with LI's? Or is the Hall of Mirrors just hard to solo? Not being able to split up those matrons was brutal.
