[QUOTE=alucard1;2810229]Yes I have tested that I can be extended to 10+ minutes. Other people have been bored enough to extend it to an hour. From a philosophical point of view you will never know if there is actually a cap or not, unless you actually hit the cap. Who knows, the cap might be 24hours for some weird reason, or maybe 1 week. But I can't see the relevance.
10 minutes is enough time to kill most bosses, and that is what this exploit is about: bring in resto shamans prior to the pull, extend healing rain to as long as you need, boot the resto shaman for any other class, pull the boss, and get heals from the healing rain. That is not a theory, that is something that I tested.
