I know there are a 1001 posts about this over the interwebz, but i wanted to share my version about this.
Version 1
Shadow Word : Barrier
1735 Mana
Instant Cast 2 Minute Cooldown
You are surrounded by a vampiric mist, making you immune against crowd control spells for 10 seconds and enabling you to drain energy from enemies.
While the shield remains you will take 90% less damage from attacks and leech 3 % health every second from up to 3 enemies within 10 yards.
Should Shadow Barrier be dispelled then the dispeller will take 25% more damage from attacks for the remaining duration.
You are able to cast spell in this form.

I'd like some decent and thought trough comments on this spell and not just a mindless rant like:
"Go QQ somewhere else and accept your never be viable for pvp"
or
"If That happens priests will get way to op, if this makes live i quit wow"
I've did some thinking about this one 'n for me it's a neat spell wich aint to op, numbers can be changed to make it match your vision how the spell would be more balanced.
Imo it's a dedent spell to get some breathing room once and awhile in pvp and at the same time be helpful to others.
Not to mention it'll make ppl scared of u for once in a while, "...omg he bubbled/vanished, SPREAD OUT !"
