Soulstone expiry reminder is pure gold though, it saved many corpse runs in PvE raids.
but even this can done by a macro.
the macro will never win a beauty contest, but it does its work.
That macro won't tell me when the soulstone has expired. Sometimes in an instance, especially in a raid instance, that can be an easy thing to lose track of. Either way, the person who started this thread wanted to know about class specific mods for warlocks... why the haters?
