I have been using scorpid sting on newer bosses for guilds since I moused over scorpid sting in my spell book a few months ago and realized it was different, so I put it back on my bar. The tank doesn't generate rage as quickly, but what does rage matter if he is dead .

Al'ar has been a pretty good boss for scorpid sting, since on occasion we have a new tank on the OT position, and he will either be slow on taunting, or resist.
