For his passive ability, it would be cool if you could "draw a pattern" where you wanted the decoy to go, so it wasnt soooo obvios its the decoy. like hold q and draw the path with the cursor. ziggy zaggy for example =)
Too complex. You don't have time for this, at least not at a certain skill level. The only think which I can come up with which MIGHT be fast enough is a select wheel, where you select different pre-programmed patterns.
