This.The argument is not "All coaching is bad," it's "Coaching has no place in a one-on-one competition."
Nope, ban it. Coaching doesn't only affect the matches where coaches are present, it can affect the course of the whole tournament.SmashMac: if coaching is such a big deal, allow the players themselves to determine, before the match, whether they'll allow their opponent to have a coach.
Example:
Player A & B are in a match, the winner gets to play Player C.
Player A is a Sheik player
Player B is a Fox player
Player C is a Marth
The score is 1-1, Player A is on his last stock with 100% and off stage, the Fox has 10% and is on stage. As the Sheik is trying to recover, his coach tells him the Fox player always rolls off too early when trying to edgeguard, so he should move backwards with his up B before going towards the edge. Player A follows the advice and rather than getting edgehogged or upsmashed, he makes it back on stage.
Then his coach tells him that the Fox player always full jump nairs over his needles and that he should use that to bait him to the edge. Player A again follows his advice, he charges needles as bait, the Fox immediately approaches with a full jump nair, to which the Sheik needle cancels and dash dances in to a grab. As he's about to Bthrow the Fox off stage, his coach whispers "Cover his forward B on stage, he uses it all the time". Player A again follows his coach's advice and succesfully gimps player B. Game Set & Match.
In this scenario, the coach saved his coachee, and successfully coached him to victory, this doesn't only suck for Player B, but Player C got screwed as well (And whoever's stuck with player B in the losers bracket). Because instead of having to face a Fox, he's now stuck with a Sheik.
So no, ban I wouldn't leave it up to players.
