Actually I recently came up with an idea for a map. It's going to be a realistic medieval fantasy battlefield. Imagine defending or attacking a castle where fiery projectiles hurls through the air and units fighting all over.
There will be catapults, ballistas, trebuchets, archers and maybe some more types of ranged units. These will be controlled in a different manner than the common way.
----------
<span style="font-size: 9px">All units with ranged weapons, including siege weapons, will have a primary Shoot/Fire/Throw button which will fire automatically when activated. You aim with another spell named "Select Target". This will show a circle (known as AoE), the smaller the circle the better accuracy because the projectile will strike randomly within this circle.</span>

I'm working on a complete thread about the map idea. I will link it to you when its done. I know that this is much more than just a simple spell but tell me if you are interested
