You have 3 allies that are damage dealers, i'm pretty sure they can push so much better than a single minion controlled by the AI. Promote is too unreliable.
In High ranked hero league, meta focuses in winning the teamfight, spreading out, clearing mercenary camps and then regrouping and winning the teamfight again, so the matches usually end before any minion can do any significative progress, you do mercs so your enemy can't do them, not because they help.
How pro players play in...
