Enjoy the moment in the spotlight but expect a nerf next patch. If there ever existed an undead shaman....well you're it.
I have yet to try to fight locks with an MS spec but with a fury spec they're pretty much unbeatable. Also I've noticed that the majority of locks on illidan are really bad. Today for the first time ever I realized that locks have something called a 'curse of exhaustion'. So how do you use it effectively? Here's a rundown:
1) seduce: shd bolt (you can also dot in either step 1 or 2)
2) seduce: shd bolt
3) seduce: curse of exhaustion
4) kite until the seduce timer is cleared
5) rinse and repeat
with soul link even upclose I could barely put a dent on them before they took me down and even rogues were falling to them.
Also, fury spec is garbage in pvp and I'd wager that so is the 500dmg shield slam (ie 200dmg after armor). It was sort of fun playing the luck game vs another fury warrior to see whose execute lights up first.
In conclusion, blizzard is terrible and still doesn't get what to do. Don't even get me started on how stupid it is to make the TOP-definining-talent-of-the-PROTECTION-tree have more use in pvp than in pve.
