its verry nice in pvp if u wanna go holy and still be able too pvp, wintergrasp and stuff :P
For only 1 point its really a tossup between other talents, especially after the buff and changes. Its good, if the DPS and healers use it properly. Healers need to put it near a place where the DPS can use it without having to run all over.
A few examples of placement...
Horsemen - in the middle of Thane & Baron so groups can top off when swapping targets.
Gothik - have your group top themselves off in between waves so you can regen/save mana.
