SilenteSI won't speak on the ruleset but I frequently see people describe rulesets as correct or incorrect ways of playing when the reality is there is no objectively correct competitive ruleset and if you think that there are aspects that are "objectively true" then sadly you are the people who will delay any real progress in actually obtaining a global ruleset. If you have only played eu rules then its more likely that you will think that if you are up at the end of regulation time you deserve to win where as na players may feel you haven't won until you've capped 5 but both are valid and have produced great games. I think there are some players in both major regions who need to be more open because holding these strong beliefs about how the rules should look just limits any real change.
fully agree with u, but the problem is that at some point it's a matter of preference in what way people want to play something and since we're in topic of 6s, i'll throw one of the most notorious difference which i see as a player and a league admin between eu and na 6s: market gardener
i made a poll about whether it should be banned or not before etf2l season 41 start and we had around 73% of prem players wanting to have it banned, while in na it's allowed https://i.imgur.com/xSv0C4O.png
of course we want to let have games on etf2l in a way people want it the most because after all the league is basically for players and we do care about our players interest, but it may contradict with interest of people from na or other regions like au/nz which may want market gardener available regardless what it gives and takes
now to the main question: i can't imagine how leagues could have some sorta agreement on that if there would be some strong differences in opinions on some matters like this one, how to deal with it?
