So, I'm in the process of being a busy little bee, and while I was making abilities, the thought came across to me about how cool it would be to have some vector targeting capabilities in SC2, reminiscient of the style in the game Heroes of Newerth. I figured here would be as good of play as any to ask whether or not it was a feasible concept to pull off in SC2, so is it?
For those that do not know what Vector Targeting is or have not played HoN, Vector Targeting is a special type of targeting that requires two clicks to activate the spell. For example, let's say you were to take a spell similar to WC3's Shockwave from the Tauren Chieftain and wanted to make it into a vector target, it would work something like the following: Click to cast the spell and the aiming interface appears, you target one point as the starting point and an arrow interface appears between that point and your cursor and the target point cast interface remains until you click the ground on another spot. After you choose your two locations, a shockwave would form from the first point and travel to the second.
