"Excessive stalling or abusing terrain to not engage the enemy is prohibited, and can be enforced by a tournament director only. This will result in a loss of the match."
Could we get a definition on this. Metaknight's infinate cape stall (which basically leaves you permanently invulnerable any where you want) isn't stage specific. If there are 20 seconds left in a match, and I infinite cape will I get DQ'd? What about 10 seconds? What about just to wait out the duration of a remote mine or proxy? What about 5 seconds, while I'm up on percentage, to make sure I get the win.
This rule is to vague. Players can do this stall for however long they want, or can't do it at all. There needs to be some clear definition, for this and other problems (wall infinites, standing CG infinites, etc).
