I don't know what it is, but every time I get a character into Moria, I hate it. I love everything pre-Moria, and love Lothlorien and Mirkwood, but there's something about Moria that makes me dread leveling a character through there. Maybe I'm claustrophobic, I don't know...
Will there be a way in the future to use alternate routes of leveling, ie. other 52-60 areas, instead of being forced into the Mines? I mean, we can level 20-30+ in either the North Downs or the Lone Lands, we can level 40+ in either Forochel or Angmar, but we're forced to go through Moria to get to 60.
