Hey guys I found a decent exploit. While in Battle of Gilnaes I was just strolling around waterworks on my horde. I went into the building with the fireplace and accidently blinked into the fireplace :O
You must be able to blink so you have to be a mage.
Step 1. You must stand at a diagonal to the fireplace as you see in Picture one.
Step 2. Blink.
Step 3. ??
Step 4. Profit.
Enemy players can melee you but cannot use any spells or special moves on you.
Enjoy.
