So after sitting on the self for over a year, I decided to fire up my old Pally. It is level 45 Ret spec with a 2H AX. I notice when I grab a mob, I hit it with judgment then start swinging, sometimes the damage is in the 600-1000 range depending if it crits, this is on a level 40-45 mob with 1600-2000 HP. What I notice is, it takes the appropriate amount of HP loss upon my first attack, then the mob gets what I estimate to 200-500 HP back. Checking the combat log I don't see it healing, or showing any HP back. It also doesn't seem to matter what seal I am using. This has been happening for the last few days.
Like I said, I am new to all the new pally stuff, so sorry in advance if I am missing something.
