I can agree with Tridus, this shield idea is a bit bad. this was the reason that SCHs were having issues: An Overzealous Potency on the AST Shields. AST is supposed to be an In between Healer, neither as good at Shielding as the SCH nor as Good as Pure Healing/DPS as the WHM.

This will create another 3.3 Issue where one healer is pushed out because the Hybrid healer is now Overpowered in an area.
