Marauder specs

Got my first taste of beta this past weekend... can't wait for the game to go live.

I had the opportunity to play my desired class, the marauder. Reached level 21 placing points in the annihilation tree, and my thoughts are that it would work out great as a raiding spec given the amount of bleed damage the tree provides as well as a bit of raid healing.

Although I didn't try the carnage tree out, it would appear now that I understand what skills/ abilities do that it might be more natural for a leveling spec.

I was curious what others thought of the different specs (rage included). Thanks for the feedback.
