From what I've read, Smart Casting means that when you selected a group off caster-units and use an ability on a target, only the CLOSEST unit will move over and actually use the spell, preventing the other units from wasting energy. Now, lets say you spot a group of high templar approaching and you have a group of ghosts; you decide to take them out using psi round before they can storm up a mess. If you select your group of ghosts, could you just hit the psi round key, target a templar, hit the psi round key, target another templar, etc, and the units will work that out amongst themselves? Because really the closest Ghost would be the one that started running over to hit the first templar- would the system be smart enough to grab another ghost to hit the next templar or no?
You would have to play the game to see what the units do. Its possible that in senario 1 1 ghost will run up and cast psi rounds unit he is out of energy and then the next will walk up and continue. Or its possible the system will select 1, and then select the next one and another and another after that. FYI, it might be easyer to click the ability and hold shift so u dont have to reclick the hot key every time.
Yes. That's the entire point of smart casting. (I played at BlizzCon 2007, so I speak from experience -- ghosts had Snipe then -- but it works that way in Warcraft III as well.)
