AoE ON/OFF please allow player to set the differ between support-spell/attack spell!

I would just like to see a much more functional spell system. I feel that having some spells aoe and some single target by default would give better time management. Instead of having to find and press an aoe macro between every spell (as I often have to do), I would prefer to just be able to cast what I need to when I need to.
I think it would make for mages who are more helpful and efficient in battle.
