Declarations of stupidity:

Paladins should not be able to use their self-only invulnerability shield. This is a bug, and it will be fixed.

Ghost Wolf is not a bug, however. The developers are keeping a close watch on the use of various speed-enhancing effects and the impact they have on Warsong, but for the time being they will remain.

Maybe you should go check if the developers are awake. Or give them a new pair of glasses.
