The basic problem with documenting the Beorning (on the Wiki or elsewhere) is that there is no documentation!
Turbine has not provided us with any Dev Diaries this time around, so everything is purely based on experience players have had with the class.
If you read the pages I've put together over a the wiki:
https://lotro-wiki.com/index.php/Beorning you will note that they include the little which Turbine has commented on the Class from the various Twitch streams. I.e. see the "Discussion" pages for each main Wiki page. Jinjaah's comments on the main Discussion page is the most complete description we have of the Dev's intentions in designing the class.
Keep in mind also that the Beorning is also a Race (not a Class), and is based upon the character in the book -- not on how it matches or contrasts with the other classes and races already in-game.
The other important thing to realize is that it is a Class still under serious development, not just tweaking. There are some significant skill changes, far beyond what most would call tweeking, which were evident on Bullroarer with the 15.1 update - damage, timeouts, cool-downs, etc.
I've only gotten my Beorning up to level 40 so far, mainly because I'm documenting as I go along, but several of the changes between release in U15 and the beta of 15.1 are very noticeable.
BTW, the "Blue Line" - The Hide - is not a DPS line, but a "tank" or an "off-tank" line. The "Red Line" - The Claw - is the pure DPS line.
And note Jinjaah's final comment:
