As an impartial spectator, I am happy that the final set will be replayed fully; I think this is the right decision and I want to see the lower bracket finals have a proper ending. However, I think that the situation was poorly handled by SOME players on both teams and that it is being handled especially poorly by the UGC League; much more poorly than the players did. I fully agree with exTine, Platinum and Smakers, as well as Stabby's words on page 2.
Rules are there for when a dispute arises and to prevent white knighting instead of being logically fair. When there is no dispute, rules aren't needed. Logically, this means that in the case of a dispute you can't just go "Well we aren't following the rules because I don't think they're appropriate". As was pointed out in previous posts, why even have rules if they are immediately ignored the very first time that they have to come into effect?
There was absolutely no need for an argument or for confusion: you apply the rules that are in place at the time of the incident and then evaluate any necessary changes later on(as Platinum more or less exactly stated). After everything plays out, you can get both of the team leaders together with a league admin and discuss any replaying of rounds, sets or entire matches between the three of them, with the league admin having the final say. I'd like to point out that if both teams just agree to follow the rules to the letter and then evaluate events after the match has finished, the team which could be considered hindered(not by their own fault) would most likely be more willing to consider replaying (parts of) the match, because there was no argument which made either party bitter towards the other in said match.
I frankly find it disgusting that (a) UGC (admin) would accuse a team who followed the rules to the letter of poor sportsmanship. In the context of the match and the match alone(excluding any events which preceded or followed the incident itself and should inherently not affect the decision making related to said incident) the rules are the only way to go at that point in time FOR BOTH TEAMS. Writing rules and then talking down to someone for applying the rules you wrote is quite simply and logically hypocrisy of the highest degree. It is a showing of a stark lack of leadership on the part of the involved UGC admins and clearly shows the incompetence of the responsible UGC admins when it comes to writing a comprehensive rule set. Please don't hide behind "sportsmanship" to hide the fact that you failed at constructing proper rules to govern your competition.
This whole situation actually reminded me of a rule in tennis which is designed to stop players from bouncing the ball for ages before they serve, which is obviously going to negatively affect the concentration of the receiving player. Since this rule was introduced(with an exact maximum of seconds denoted), there have been many instances where the referee is too lenient with the amount of seconds, resulting in the receiving player complaining. Whenever the rule had been followed, the serving player would sometimes get a bit upset in frustration, but would eventually accept the decision. As time has gone on, complaining has almost completely stopped by both receiving and serving parties. I think what can be learnt from this is that if you enforce a clear rule, competitors will eventually accept it without any negative feelings and that negative feelings mostly arise because of a lack of a clear dividing line maintained by the refereeing party in sports... and that includes e-sports.
I also feel sorry for the players on both of the teams who have received flak for things they tried to stay out of and remain impartial to.
tl;dr: Rules are rules. Enforce what you have, then discuss civilly if it wasn't satisfactory and then change them after the current competitive calendar draws to a conclusion.
