What about single-target group party buffs?
I'm running a 4-box (all my resources can handle right now) with 2 pallies, a mage and a lock. I'm wanting the pallies to buff themselves (already figured this part out with a single keybind). However, I'm also wanting the pallies and the mage to cast buffs on all other party members. I'm running into problems with /click, as it's trying to cast all the buffs at once. Any ideas on how I can make this work w/o an addon while still maintaining a single keybind for party member's buffs?
