Well, this is more a less a simple, common sense trick. But, I am surprised as to how many people actually don't know this trick.
Basically, EVERYONE in the raid has a level 20 warlock. A set of raiders then log onto their locks and SS a set of people in the raid. The next set of raiders log onto their locks and SS the second set of raiders. Thus, everyone in the raid has an SS
This is quite simple, quite useful, but also at the same time, its nothing too special.
High level raiding guilds use this trick and my guild actually has used it for big bosses. Saved our butts.
