Please don't reply to hand holding posts, it just gives us more to clean up. There is a DPS Analysis thread that would be the correct place for them to have posted this. Also don't do the @Twitter thing, we have a quote function for a reason.
@itzFrank - You use Explosive Trap solely on Yor'sahj, since he never moves - at least on normal. You get more LNL procs, and thus more damage. It doesn't matter if you get black everytime, or never get black, it's still better since he literally never (needs to, anyway) moves on normal.
