personally i've gone for energy mastery with mine and taken physical perfection and focused acc. 6 gaussians (i appologise for my poor spelling btw) in focused acc for the +defense and got 4 numinas in PP, but still tampering with those. I also have hasten in my build to keep my heals coming back faster, recon is down to 16 seconds and DP to about 100 giving a 20 overlap of +hp, hasten is also only 1.3 seconds away from perma.
