LoH nerfed on PTR, no more usable on self.
Check MMO champ and the NA forum.

Holy
* Sacred Shield can now only occur every 30 sec. (Up from 6 sec)
* Lay on Hands can no longer be cast on yourself.
* Infusion of Light now also reduces the cooldown on the effect of Sacred Shield by 12/24 sec.
* Aura Mastery now lasts 6 sec. (Down from 10 sec)

Our best BG/world pvp cooldown (eventhough not usable in arena) is gone.
BG and world pvp will be serious business in cataclysm so this is definitely a nerf.
Not to mention the raid wipe saver utility.

We better get something very, VERY BIG in return.
