TL;DR- I think the current league rules are fine. I have limited comment about tournament rules because I rarely am available at tournament times to participate.
I think that the rules being different is fine. Consider the differences between league duels and matches and those in a tournament. In a tournament, your winning or losing the whole thing could be defined by one d/c or desync game result. The stakes per-duel are HUGE in a tournament compared to a league season where players wanting to win should be around 2.5 duels per match with 15 matches required (many play more) --> 40+ games/duels in typical league seasons.
I do not know what sort of issues are being reported or going on behind the League scenes, but as for my matches I would _never_ get so heated about a league duel to take it to turn-by-turn arbitration to decide an outcome. If the opponent didn't want to grant a win where I feel I have a legit case on it, we replay (per rules) and if I win I win if I lose I lose. And future instances of that opponent wanting any benefit of doubt would be gone.
I make sure to note and post about fair play instances with players for this very reason (in cases where I win the match and get to post, of course). Some matches have no instances of anything going on (no d/c's, no desyncs, no win-win or loss-loss scenarios) so no comment but any time I experience an opponent being fair and reasonable as it relates to d/c game outcomes and the like I post about it to encourage further behavior like that as well as begin to build a trail for that opponent of how they play fair should a future opponent decide fairplay begets fairplay returned. I have yet to encounter any unfair treatment or cases where opponent is being extraordinarily demanding or refuting in League 2/2018. Suffice to say I would have no qualms posting about it should it be a match I win - with great consideration given to posting about it in an S&F thread should I not win the match.
^-- my thoughts on it, kaempfer
Added disconnects to rules. It is the one where both players take winscreenshots like you are probably used to.
Now a question is, for desync the rules for tournaments and league do not match. Here you are supposed to continue same as with disconnect even if the boardstate goes completely haywire (Like creatures spawning out of nowhere, stuff geting protected with no earthquanta in the deck etc). With league time constraints for rulings arent as important, so its possible to evaluate turn by turn screenshots after desync, making it possible to make a case by case analysis for desynced games. That however is definitely more complicated for everyone than the typical alternatives of winscreen (current rule for leagues) or replay (for tournaments).
What do you guys think?
