If you're having issues with focus, you're doing it wrong. You should be able to build quickly and maintain. Adjust your rotation instead of button mashing. Auto attack is a thing of the past. At least it should be.

I believe it is an exaggeration of a Force Lift that broke early. If you spec into Balance you can get the skill Containment which stuns the target of a Force Lift that was broken before the duration ended.

Willpower and Endurance in that order are a must, but that's a given for all Consulars. Crit is then the priority for the Seer. Then after that I personally go for alacrity to boost my Deliverance speed, but I've heard others say otherwise. Up to you after Crit I guess. You said you were having issues maintaining force? Around level 36 you shouldn't have that problem. If you spec all your points properly into Seer thus far, you should have spent 27 points allowing you to have both points of Resplendence. If you don't have both points in Resplendence yet, respec. If you are planning on healing your way to 50 from here on out you need this talent. It will turn you into a Force Battery. I personally did not add points to other trees until i got Salvation in the Seer tree. Inner Strength is tempting at first, but wait till you spend 31 in Seer.
