I PVP with the following:

18 shaman twink Eaterovdawn that  PWNs WSG

29 mage Dalmchd that has less HP than my shammy and gets 2 shotted by twinks, so I sheep and suicide AOE (able to burn most of my mana before I die.)  It is a BLAST to assault the mine from the air as I slowfall from the cliff above (can't get hit until  land) :twisted: 

Rath hasn't engaged in much PVP since level 49.  
The reasons: 
I wear the healer bullseye, and when I do DPS, I do enough to become the must kill target, and get 3 shotted by any allie that isn't a healing class. My survivability is zero, and my repair bill is exponential.
If I could live at least long enough to go OOM I'd be happy.
I went shadow to see if it would help, and it has, a bit.

All of that aside, I'll go squish allies with you  :D
