This rule seems stupid to me.
Avoiding the debuff: Sitting at the dungeon's door waiting to be kicked because you don't want to do it, forcing people to kick you so you can avoid the debuff is now punishable. Rather wait 30 minutes than a day.
Why can't you do this? Wouldn't you prefer someone explain to you that you should kick them because they don't want to play? Anyone can circumvent this rule by just logging out for 5-10 minutes.
Having people log out without any explanation because they are avoiding a ban under this rule is far more toxic than them simply explaining they have no desire to continue.
This is clearly not exploiting a bug. It is a game mechanic. If you queue with your friend and the RDF team kick him because he wants an item they want there is nothing you can do to report them because there is zero proof even though it is against the rules. Yet they can then get you banned if you tell them you'd like them to kick you too so you can continue playing with your friend. Your only course of action is to just go offline for 10 minutes. Why are you just asking every player to become a warmane TOS expert because these rules don't even prevent what they are supposed to prevent.
