If one suspects any game abuse (in any form) that would result in the remake of a game, it must be reported to the TOs BEFORE the next player takes his/her turn. It is NOT considered reporting to complain or remark in game chat or the public forum.
That's a bit harsh imo.
I am sure at least half of the players engaged in the CC cup didn't read the entire rule thread.
And among those who read it I am not sure most of them know every rule of the section.
It's very possible the next player playing doesn't even know it was a broken rule but just assume it's just a shitty move, and therefore would proceed with his turn without warning other clanmates right away.
I've seen people complain in our internal clan discussion about a move of someone that could've been breaking a rule but still played their turn before any of the people that knew it was a broken rule could've responded.
Also one may not have so much time to wait before playing this next turn.
Player A breaks a rule. ~12h later player B see the turn, but only got 1-2h to play before he needs to go to work/life event/whatever and therefore cannot wait to discuss what happened otherwise he risks to miss his turn. He plays and then the player A gets away with it. That's not an uncommon situation for many people to not have tons of time to wait before player their turn.
I would rather that the CD examine the situation and the impact of the game rather than just have such a restrictive written rule.
I understand the reasoning that you to prevent that a clan could see a broken rule, play a few turns to see how the game turns, and then decide to ask for a remake.
That's why I think having a fixed rule like the one you just wrote isn't such a good idea and CD should just judge on a case to case basis. CD know should know enough of the game to see the difference between a meaningless running out of a time in the beginning of the game, and one with a decisive impact on the end of the game, to be able to judge fairly.
If you think it's not possible, I would think giving at least 24h for the other team to make a request for a game to be remade is much better than asking "before next player plays" since, there is always less than 24h remaining when next player see the game after someone played. ( and sometimes less than 12h).
