May I suggest you use the report feature instead of trying to moderate the forums? I moved these posts here, which was my mistake, they were part of a Cata thread before we split off. Deal with it.
Leaving your post since you bring up additional points.
As this is the WOTLK 4.0 thread, not the Beta thread, I think we should skip the commentary on Thrash, which doesn't exist on live (and won't until the expansion).
As for reforging dodge rating, in general you won't need to, because in general you won't have anything with dodge rating on it to reforge! That is, armor/strength/dodge items no longer do much for bears, and we are better off replacing them with agility items. This is mainly because the bonus armor on items was greatly decreased (in at least one case completely removed), at least on all non-armor items (our armor hasn't had bonus armor for quite a while, so I don't know about those), and agility items now have the stats that are more useful to us. This includes cloaks - while the total armor stayed the same, the armor rating on the non-tanking cloaks all went up (and the bonus armor went down).
The only place you're likely to find dodge now is on trinkets, as a choice versus stamina trinkets. The benefit of dodge trinkets is you can reforge them, so the question is mostly back to the age old stamina versus avoidance. With the removal of the chill of the throne debuff, avoidance is looking better than it has.
One of the benefits of feral druids is that we use fairly similar gear for tanking and dps, and this is one nice thing about mastery rating - it's a good stat for both roles. As a kitty primary, bear secondary, I've been replacing the armor/dodge items with either leftover kitty items, or in some cases current kitty items (where the leftovers simply didn't have a strong stamina or armor advantage).
