I see no reason why Cures and Buffs could not be automatically Area of Effect at all times.
There is no penalty to MP cost for the AoE version of spells. There are no instances (so far) where a nearby player would not want to recieve a buff or cure.
Toggling AoE on for Cures, then off for offensive spells in a crowded area, than on to cure again, requires complicated macro sets when using a controller.
Another option is for Cures and Buffs to be on a separate AoE toggle then offensive spells. I would then leave the AoE toggle on for cures and buffs. For offensive spells, I could then focus solely on nearby mobs that may be hit with AoE, and toggle respectively.
/ac "Cure II" <st>
This allows me to select a traget for AoE cures but not have the next offensive spell be AoE. This is not ideal when I WANT the next spell to be AoE. Then I have to go tggle it back on between after cures.
Implementing a AoE toggle for controllers, the commands <stnpc> and <stpc> and having Cure and Buffs auto-AoE would be perfect. Following up on the promise to make players targtable through the party list would also be helpful.
Edit: The bolded text seems to be a more prudent option, considering the feedback thus far.
