Note: Blizzard does reads these post (they really do). So I am asking everyone who has an idea to improve the priest class, or make it more fun, to add an idea to the post. Keep it realistic, keep it unique, but please please please.....keep it limited to only ONE idea, per post. I see awesome ideas get lost in a sea of bad ones. So lets go!
Shade (semi-travel form)
Mana Cost: 450
Cooldown: Instant (Cannot cast in battle)
Highly increases the priests speed, and decreases the priest visibility in areas that have overhead coverage (forest, dungeons, inside buildings, etc). While Shade is activated, the priest gains a 10% critical bonus to the initial spell cast. Once priest exits a shaded area, he will lose Shade form.
