I'm lvl 48 and just wanted to share a fun experience. I haven't PvP'ed much on my pally. My main is a mage, and I love to PvP there. I'm leveling my Pally now and decided to stop in to the WSG BG on my way up. Now, my experience from a mage was all fine and good, and rogues and warlocks are my mage's bane. So, here I am in a BG and *pow*... Cheap Shot. I am thinking 'oh no'. I put up holy shield, Blessing of light and judge, then blessing of light again. My shock came when the rogue tried to run away (HoJ) and then vanish (Consecrate). He almost killed himself by beating on me. That was fun! I walked away with a few chips in my shiny plate armor and left a dead rogue on the ground.
Quite fun!
