The +damage form is not really a great deal. As a brute, with fury, it becomes even less obvious.
But the forms from Staff Mastery (the power) are worth gettung. The end reduction form is great while leveling up, or for long battles. The bonus damage can be nice too..such as teh Psi damage, vs something that has just used a tier 9.
I usually play in Form of the Body (staff/wp scrapper) and alternate the -res (aoe finisher) and +res to self (skysplitter). I find this the most useful, and totally worth the pick.
Besides, I know Staff Mastery is a gimmick...but without picking it..whats the point? Buying a set and not even using the selling point? I ran into a lvl 50 tank..invul/staff..with NONE of the staff aoes, or staff mastery. SO he was left with..3-4 single target attacks (and the ST attacks in staff aint amazing).
If you need extra convincing..the pretty staff spin animation, when you change form with your weapon drawn. Worth the power pick alone.
I tried form of the mind as soon as I got mastery and the recharge rate increase was noticable but I kept running out of end.
Is Staff Mastery worth taking? YES.

staff mastery is wonderful.
it gives you tools for different situations, use them!
myself i hate downtime and form of the soul virtually eliminates downtime for me with even the most end hungry secondaries. case in point: maneuvers, tough, weave and combat jumping with dark armor before level 30 and running around non-stop smash - was never able to accomplish that before.
staff mastery makes for more SMASH. SMASH is what makes a brute.
it's not just worth taking, it's a milestone.
I have questions about SF/FA Brute i have...
1) Is Staff Mastery worth taking for the 3 buffs? (I know, only can use one at a time)
2) With the damage boost, the body one, how much more damage would i do from it? A Percentage would work if possible...
So far, I am Level 28, and loving it so far, Spring Jump, Burn, Eye of the Storm, DEATH..even before EoTs there dead pretty much.
I Do not have Staff Mastery at the moment, and in my opinion, im doing just fine without it.
Other thoughts i was having though to, even if it is a little bit of damage, its that little more help, plus Fiery Embrace, plus the damage buff, then having Rage ontop of that, i think that sounds really good.
Please, anyone, share your thoughts and suggestions, i would really appercaite it.
