This is largely a PvP concern, although I would love to be able to bring my Felguard into a raid instance and have him last more than 3.5 seconds. Every piece of armor my lock adds to her kit should buff her pet as well as her own locky self, it only makes sense. Well, that's the way it should be, but it's not working properly, and the locks are looking for some love. And before you go there, no this isn't a call for a buff, this is an example of a bug that needs to be addressed, and has nothing to do with whether or not locks are overpowered.
The good news is that the devs are interested in hearing what you locks have to say on this issue. This is one case where they are asking for feedback and suggestions on how to improve the situation. Of course we're talking about constructive feedback, so Neth asks that you keep the complaining to a minimum if you want to have your voice heard.
