A new Lord of the Rings Online guide to early levels of the Champion is up at Myndariel's Middle Earth.
I've managed to get my Champion character to level 30. Reading the guide is super helpful though. One of the things that I've had trouble with looking at my LOTRO characters since I've returned is picking a Specialization for my class.
I'm reading the descriptions, of course, but it feels to me as if they split up what the characters used to be able to do into these three groups that all have desirable skills, and I want them all.
In the case of my Champion, it appears I've been choosing from the red Berserker specialization. Reading Myndariel's description of how the three specializations play out, the yellow Deadly Storm really is best suited to the way I play. I'll happily switch!
