I like how a bunch of people act like they are in a position of authority and claim how "un-smash like" it would be if they actually interpreted the sentence in the most logical form. Sakurai clearly stated it "can be performed but once…." If it could only be performed once per ball, he wouldn't have had to say anything. It is to be assumed that a final smash would have been used one per ball otherwise. Obviously he stated "can be performed but once…" for us to know that you can use it once per match.
Ironically I'm going to use the position that most people debate against me on in other Brawl debates, and that is Brawl is a "new" smash with "new" additions and it will not be like the other two. You can argue how the "final smash" wouldn't live up to what you believe smash is all about just like you can argue the same with wavedashing, l-canceling, and all that. The thing is, you guys aren't Sakurai, and unlike wavedashing and all that, Sakurai came out and said you can only use this once in a match.
Also, most people play this game within a 5-10 stock match limit. I've been to A LOT of anime convention tournaments and this is what I typically see. That's about a 10 minute match, with 4 final smashes. Imagine how much damage 4 final smashes would cause in a FFA? Quite a bit. If it was once per ball then the entire game would revolve solely on evading and grabbing all the final smashes. Now if that doesn't make the game ****ty for FFA I don't know what does.
Oh yay, lets have someone bash competitive play! Oh wait, you don't know what you are talking about! Some people, myself included, see the Final Smash as an item that would add more depth and strategy to the competitive scene. Why is this? Simple. The item has it's own limitations. It can't be abused over and over again, which would make the entire match break down into grabbing final smashes like I said earlier. It could be used strategically and would make matches exciting. I'm looking forward to learning how the Final Smashes work, cause I really hope that they are an item that can be used for competitive play.
OH NOES! I might have be strategic with an item instead of grabbing them all the time and playing dumb!
I just wish people would have a little more common sense as well as an open mind about Brawl.
