I actually like this idea. Targeting lines would be a nice feature, but battle/target windows are a must! It would make targeting so much easier! And the traditional battle menu is present, that would make choosing spells/items nostalgic and like old times. And give us a reason to have potions in the game xD

But no gambit system. Battles would become more automated than in FFXI, and that would be a problem. I want to actually play out my battles (aside from auto-attack, I still want that at least).
