A player having the right to concede at any time is literally part of the formal rules of Magic. See (rule 104.3a) here: https://media.wizards.com/2025/downloads/MagicCompRules%2020250725.txt

I do think a better time-out system could (easily) be implemented on Arena and have long-advocated for it. Most recently here: https://feedback.wizards.com/forums/918667-mtg-arena-bugs-product-suggestions/suggestions/50442951-question-%C3%A0-woc-et-%C3%A0-la-communaut%C3%A9 .

Atm, there are also a few platform-specific bugs that also lock-out further player actions so their only option is to "concede by quitting the Arena app" which (atm) unfortunately leads to a "roping experience" toward their opponent. They are (generally) also unable to re-join the game and get some version of this screen (see attached) instead--not a good look and an bad experience for all involved.

That said, those are a (relative) rarity so I do think it makes sense to impose some sort of "roping time-out" session throttling penalty (10 minutes?) for that particular client-id akin to receiving a yellow-card in Rugby.

Atm, I just insta-concede to repeated ropers and add them to a manually maintained list of "known bad actors".

Sans être aussi radical, je pense que le "concéde" ne devrai être utilisable que lors du tour de jeux du joueur, si le joueur veut concéder la partie qu'il le fasse lors de son tour de jeux et non pas jsute au début du tour de l'adversaire comme des petits frustrés de la vie le font.

Je suis tous à fait d'accord avec votre idée, cela devient insupportable de subir ça parce que des petits névrosés qui remplissent les poches de cette entreprise font un "caca nerveux" quand ils se rendent compte qu'ils n'ont plus aucune chance de gagner.

While I agree, that intentional roping should be punished, conceding at any time is a player's right regardless of reason. You do not have the right to force a player to play against you. And punishing players who due to the client's malfunction or other factors out of their control is also unjust. Not everyone is intentionally roping. Many are trying their best to get back into the game as fast as possible, something the client makes extra difficult already by wasting time with slowmo "animations" instead of letting the player back into the game, and you want to add a 30 min extension to that.
