Now, before you yell at me, yes I did check with El Goog regarding this topic, but I have yet to find exactly what I was looking for, so, here I am.
I have been using a help / harm macro extensively with great success. It is as follows:
/cast [mod:shift, @player][@mouseover,help,nodead] Renew; [help,nodead] Renew; [harm, nodead] Shadow Word: Pain; Shadow Word: Pain
I have even replaced Renew & SW:P with Penance for those situations (where Penance is required).
However, it has recently occurred to me that adding a Focus element to it might be even more delicious. I don't feel that I need to have Focus in the 'harm' portion of the macro, but I was wondering if the healing side could be prioritized thusly:
Self w/ Shift > Mouseover > Target > Focus (maybe the last two should be switched?)
Admittedly, I have little experience with the use of Focus in general, so I am open to suggestion with regard to its' placement on the priority totem pole. I suppose I would also be open to having it attached to Ctrl, for example, but I really think I'd rather not have to think about it even that much. All I know is, I'm tired of stopping to loot and then having to locate and re-click the tank before s/he gets her/himself killed.
Your assistance is greatly appreciated.
TL;DR: Can I add a Focus mod to the above macro so that I don't have to continually re-target the tank?
