Well Surge and power. Simply because of diminishing returns........ You want your Crit around 300 and your surge at least 250, while balancing your activation time. You want to hit harder with your heals, instead of tons of smaller heals. This really helps with interrupts, as you don't have to cast as much, to heal the same amount. Plus you can always supplement your activation time with the rakata alacrity stim and relic.....
