Shun: first, I think you meant to direct that at me, not Pierce. Second, it is funny you say you shouldn't have to worry about the 7% chance that a situation will occur, because that is roughly the percentage of Gordo's that D3 will throw (probably a little less) and you cannot possibly expect a Gordo every time D3 presses a button. Additionally, with D3, you actually can have almost zero warning, easily less than you get with Picto's transformations because the draw time for a transformation is more than the start up animation of a Gordo. Moreover, when looking at Peach, you certainly can't prepare for Peach throwing a bomb every time (of course this is slightly different since Peach first has to pluck and hold the bomb). Regardless, my point is not about what is reasonable or not because that is subjective and everyone will draw the line slightly to extremely differently, it is more that randomness is already an accepted, and more importantly, inherent factor of Smash and has been in tournaments for years upon years.
For example, I remember when Chillin almost quit playing Brawl because the ghost on Yoshi's saved Blackanese after he had wasted his up-B as Olimar and was falling to certain doom. Chillin had the match won, he even put his controller down! It was certain victory...except for a random variable that decided to pop up like a miracle. Is the randomness on Yoshi's acceptable when there is evidence from this match and countless others that its randomness "unfairly" changes the outcome of matches? Where do you draw the line?
pPp Suspect: I think you lost on PTAD probably because you didn't know the stage. PTAD is a good MK stage but definitely not better than Brinstar or Cruise or probably even Delfino. On PTAD your weight as D3 should give you a substantial advantage when it comes to surviving hazards compared to MK. MK's only strong point on the stage is sharking which is something he has on several stages. Regardless, MK has the advantage on basically every character on every stage so that is a pretty poor reason to ban something, especially when there are legal stages that MK has larger advantages on. Banning MK would solve a lot of problems but it would also cause a lot of drawn out drama and debate. Shrug. MK is dumb.
