my point is there is no reason to hit that dr peak on CR because from willpower you will have more than enough Crit
DR curves have no peaks.
any good sorc healer will tell you they pretty much have force bending proc on permanently which remove the need to have maxed CR somewhat.
Having force bending on permanently does not remove the need for crit chance. Crit chance will give you more crits, which, can be more favorable in terms of healing output if balanced appropriately with power. Who's not to say that your choice of 120-125 crit rating is too high?
