Shadows of Angmar looks AWESOME going by the screencaps that are up on the site.
I love playing mmorpg's and strategy games; Middle Earth and Middle Earth 2 were fun for a while as well, but I've really boon looking forward to this.
Of course I've signed up for the beta.
The only thing I'd like would be if they let you play as an orc, troll, uruk hai, etc. like in WOW, but that may have to wait for an expansion or something major. Right now the class systems are good, but I'm conscerned that they might follow the gender-sensitive character profiles of Diablo 2; you can only play as a girl if you want to be a Captain, Burglar, or Hunter.
Also, I'm a bit concerned about the possible proliference of NPC dragons and other such enemies; they usually have the best loot and experience, but games run the risk of of having a drought or a proliference of such beasts, and the fact that LOTRO.com lists them as their own class of encounterable enemies is not a reassuring sign for those of us aware of the fact that there are no dragons living at Weathertop.
