Burglar can solo very well. Just being able to Hide in Plain Sight saves your butt so many times when you get too many adds. I soloed most Himbar quests (Spiders quests too), swords quests (except 1 or 2) most all the Angmar quests that require collection. Getting to places as a Burglar while might not be as fast - we can sneak past mobs to get to the nastiest of areas. I have gone past some nasty elite trolls, etc and then even if they see you, you can use HiPS to escape, or mez it and run. Signature mobs are the norm in some places in Angmar, and you'll be plowing through them. It gets better after 30 and when you get HiPS. Then at 36 when you get ready and able you can refresh your skill timers which makes you even more deadlier. I guess it really is a personal preference, but then again I think you need to decide early which class you prefer. I made a Hobbit but am going to put him on the shelf for the Man Burglar (3k heal once an hour, 1% evade & parry Man traits).
