Don't see why any shaman would be upset about this. Youre SUPPOSED to be able to kill it.. Just not via an automatic spam button bound to every spell on your bars. Great addon really wish there was a default option to turn off nameplates for snakes/totems makes for messy screens.
I'm getting pretty sick of this exaggeration. No good warlock would ever do this. And if a warlock did do this, you should have jumped for joy because now you have complete control of where their pet will go.
