Re: stay BS: deepthunder or go enchant for +20 healing rings for pvp!
Personally I'd stay with the shield and resto mace since you'll gain a decent amount of spell damage from it when the patch comes to (as you put it) "hopefully shock them to death".
Re: stay BS: deepthunder or go enchant for +20 healing rings for pvp!
A resto mace and resto shield won't make you a good healer. You'd gain maybe 300-500 +healing, depending on how good your resto gear is. That's not enough to make a really big difference in your heals. You'll already be getting a decent amount of spell damage and healing from your AP anyway (I forget the name of the new talent that will allow this).
Unless you're frost shock kiting a warrior you'll just want to stick with either deep thunder or a good melee DPS 1h with a shield. Against any other class, between healing and shocking, you'd go OOM before you had a chance to take him down.
