you know if you set up your macros right you can just smash the "heal" button until you see enough HOTs rolling on your tank and then smash the dps buttons again. I did that with my shaman. They all had a heal and dps button and since they will go out of sync when doing /castrandom dps it worked out well for healing. I would hit the heal button until I got 2 dps to start casting heals and then I would go back to mashing my dps button. That way dps continued on 2 shaman while 2 healed. I think Hachoo is to thank for this idea, it works great.
