If I remember correctly, I did most of my playing in the mid-40s with the Herald of Hope (who is the most survivable off-tank of the bunch). 4 red traits (and Now for Wrath, if you have it) are a must.
The first quest hub in Forochel is meant for level 44, so you should be able to pull it off.
Have you finished everything in Western Angmar? There are a lot of quests there, and not too many that require a full fellowship. It should be possible to form a small fellowship there. It's in East Angmar where everyone seems to disappear for greener pastures (LIs, class quests, Forochel, etc.).
I do not love the bright sword for its sharpness, nor the arrow for its swiftness, nor the warrior for his glory. I love only that which they defend. ~ Faramir
Undo the U12 class changes. The trait trees were, are, and will always be a bad idea.
