Ok so my 10 man group of level 86 enh shaman kept getting wiped by a single (well geared) shadow priest. Honestly the problems I was having I'm not sure it would have mattered if he had blue pvp gear. Anyways I have frost shock on round robin and this dude kept getting away because he would either:
A. fade (can't cast spells on him for a short duration)
B. use rocket boots after a frost shock would hit
C. Use that doppleganger move (I forget the name)
D. Mass Fear (this was the worst)

With A I would just wait it out while chasing in wolf form. With B there was no way in hell I could catch him, rocket boots are so ridiculous in world pvp. C would give him enough time to lose combat and mount. D.... jesus christ on a pogo stick this one pissed me off. I had dudes all over the map dying in random places to all the aggro from mobs. This was by far the most frustrating part of this ganker. After getting wiped 4 times I got pissed off and logged in my DKs and ganked him for an hour straight. He would get away, but stupidly come back for more. I don't know how people think they can take on 9 Dks and a priest by themselves. O.o

Anyways one thing that I felt was just not happening right was my frost shock root. The person who was next on round robin was usually out of range due to fear, wacky IWT or dazed due to aggro from mobs. I realize these guys are only 86, but I felt almost helpless against this priest. I need to figure out a better way to round robin frost shock so I can guarantee a root. I'm not even sure how to start? It needs to check that it was successful and if not, move on to next shaman to attempt another frost shock. Is that even possible with ISBoxer? Of course I don't want it to spam FS or he will just become immune.

Maybe I shouldn't even bother as when I get Ascendence that SPriest will be toast. Melee from 30yards is so sexy. Thoughts?
