A fellow Warlock in my guild has been having connection issues when using KC. He gets disconnected periodically throughout the raid when channeling any spell while moving. I do not have such a severe problem, however I have noticed lag spikes whenever I begin casting or channeling and move within the GCD. Also if I start moving within the GCD of casting or channeling, my channel bar disappears, I can still see the spell effect being channeled but my cast bar is gone. If I cast Haunt and start moving within the GCD I get a lag spike about 75% of the time. Anyone else having this issue?
