Most people seem to just want to null the entire concept of variations
IMO concept of variations is what we as community and TOs will make out of them, unless NRS will come out with their own tournament mode or specific rules for repicking in online / facwar games, because community then will definitely take them as default and maybe will tweak in the future.
We've had things like this before where players still went into matches not fully knowing the rules. If there's a bunch of different rules per tournament then players may end up getting confused. An example of this is Injustice and stage counterpicking, there were a handful of tournaments that did it differently and players would use the method of a previous tournament or something.
I don't always pay attention to tournament announcements, but most of those I see contain location where it will take place first, rules second, and only then you'll see the rest of crap. Honestly, even if we can agree on something here, you will still have to make sure that this another TO isn't going for something original, so...
Honestly, I believe we should ask mods to make sure that whoever posts what looks like tournament announcement also adds all the info that is needed. We can even provide a sample and sticky it.
Stage should always be random regardless. I'm sure everyone here agrees on that at least.
To this day I'm still not sure if IGAU even has random stage select lol.
When you sign up for a tournament... You have to sign up your character also... Then you cannot change anything ever and if you do you are banished from all existence.... This seems fair to me..
I heard that's what japanese do. Expect at least one such tournament to show up.
Actually, I've even seen such tournament for MK9...
And inscribe rules on it. Then plant said pole at the entrance, wherever your tournament is held.
Seriously this is easily the best option. What is the point of variations if the rules end up being "absolute variation lock"?? Might as well not have them at all.
The point of them is to be picked, I believe. Not that standard set of locks would somehow thwart that
But seriously though, don't worry. People will definitely try to use this system to make fights more diverse if it will indeed be proven to serve that purpose.
