Yeah i do agree.
One thing I think is waistful is if you dont have you force regen procs at 3 you can't cast an instant salvation but if you use it before the three or dont use them to regen force they just poof if you cast a channeled salvation.
I never did understand why it takes them even though you get nothing in return.
But yeah i agree with you there should be more emphesses on using the bubble.
