I'm not sure how good a time this is to ask that question.
The class just had a radical change and will probably see more changes in the next few months to fix what these changes broke.
I solo'd red line before with no problems (other than that itemization for Beornings had been broken or just missing for long stretches of the 1-85 game; don't know if the heavy armor changes will fix that now), but I don't know now with the latest patch.
I say play around and learn along with the rest of us.
