Why can't we have an undo button again?

Cool discussions... Even philosophical!
From reading the above and game experience, most errors occur at spanning and attacking. I like current game control as I hate stupid confirmations. But a double click or something would be preferable as a solution to prevent it (first: highlight unit, second spawn or attack), a pop-up would bother me too often.
But I like playing for fun... Even if it lost me several tight league or world cup games. DOH!
And the cost:benefit would not be good... Would not advice that to invest in.

Just think of the positive side of it: if you loose a game by mistake you have excuse, if you win after your own mistake you can feel heroic! ;-)

Enjoy the game, all! Cheers
