I played my SS/NRG Brute without stamina for quiet a while. You will be relying heavily on Energy Drain, Conserve Power and Overload. I found myself alternating Conserve Power and Overload (my end bar hardly goes down wehn using either) and using end drain as and when necessary. End drain works so much better in large groups (do you mostly team or solo?). Maybe consider more slots on End drain as you will be relying on this a lot, another recharge reduction and/or End Mod?
In the end I did get fed up playing without stamina and respecced into it by the way.
Try looking into this guide, bud, and it might modify your build.

You don't need 3 IntRdx in Aid Self, the interrupt time is fairly short, I'd go with 3/1/1/1 heal/int/rech/end. Or possibly swap that 1 end for another rech/int.
I 6 slot mine with heal/int/rech all having 2 slots.
It means I an heal approx 45% health every 30seconds (ish).
Plus if timed right it can also be fired off in between damage ticks from DoT 
As my EM/EA brute is coming up to 40 I was wondering if I could do without stamina so came up with this build.
