I think that’s a dangerous precedent you’re setting there. Especially if you don’t retrospectively amend ALL other rule changes for ALL other submissions for ALL still actively contributing events.
As an example of the implications that this will have:
Lets say player A won a Modern league. This will increase his rating, which in turn gives a boost to any other tournament he enters, meaning that whoever competes in that second, or third, etc., tournament is getting additional points based on the incorrectly awarded boost from the win at Modern. Every player then carries this boost into every other tournament they enter.
Are these all going to be rolled back?
I think that the stance should be consistent with previous rule changes: The rules have changed from “this specific date”, we’re not going back and changing anything before then.
This is the answer I’ve received when querying previous rule changes.
Every single rule change will negatively effect some people and positively effect others.
I have to say that this looks like bullying Modern, who’s going to be the next target, because they’re not in the “cool gang”?
