Well the big thing regarding is the 36 point talent which gives you passive bonus per point spent in the tree up to 51. I would say some calculations will need to be done if it out weighs the bonuses from lower tier abilities from other trees.

I do know from tests that i have done that it is better to spread points out over the three trees at least up to level 15 for the 1st tier bonuses. I based this information from dps/healing reports from warfronts.

Havent been bothered to install the 3rd party parser yet.
