Don't see why the macro system couldn't be adjusted to go with this. Imo AoE-everything is part of the reason why DoM are so poorly designed in this game. Especially with healing as you can just spam heals on your party without really worrying about enmity or MP management. Don't think they can't make adjustments to other parts of the game to make something like this work. Really I just hope they rework classes and combat altogether.
