Crit is not your best stat, its miles worse than WP, stop trying to stack it you dont really need to, yes there are things that proc off crits, but the math thats been done at the theorycrafting sites clearly shows that WP >>>>> all other stats.

The default 7 points out of the main healing tree are pretty standard, already.
