Newby is a lv46 nubsauce. Xalis would eat him.
I take it he rolled a warlock?
Stunlock FTMFW
If you are perfect at stunlock you can kill a warlock unharmed :-/
The only case a Paladin can stunlock something is if it can one shot it. We had a 6 second stun on a 1 minute cooldown, and that's it, other than I guess Seal of Justice which sucks in PvP. Unless you're judging Seal of Command, which I've found useless now that they've buffed Seal of Righteousness.
