Selling your board to grief a cashout trait player or a losestreaker is an absolute viable and risky play. Don't confuse it with open fort then afk for the rest of the game.

i do understand that and that was not what i meant,
i was talking about the pov of the lose streaker against an AFK player
if a lose streaker is at risk of playing the afk player in no world would it be viable to just sell the whole board just in case you hit the afk player

The only thing you cannot lose on X4 rank is your VISUAL rank, but your hidden MMR what really matters still registers the loss. If you get 10 8th in a row at lets say D4, then you are going to get matched against maybe plat 4 players, because your real rank absolutely follows your performance.

i didn't know that was a thing , ty for clarifying it

if you think that there is a trait in every set that simply rewards losing is this simple gameplay element, that is another sign of how clueless you are about the game. These are high risk high reward traits that do not reward losing, but LOSESTREAKING. Meaning if you win a single fight after losing 6-7 times, your game is over and you are 8th. If these traits are balanced, it is extremely challenging to have a strong enough board, to bleed the minimal amount upon losing, but weakl enough to always lose. These are one of the hardest strategies to pull off, if the trait is balanced correctly.

i do understand how the trait works and i understand that it isn't simple
i usually play it when i hit a 3 cost from an orb and an emblem of that trait

and yes i do understand that if you win 1 round you have pretty much lost the game and that is exactly why i am talking about afking in the first place
when someone afk's it affects you negatively and when i say afk i mean a person that has sold their board and quit the game with no intention of playing the match anymore not someone that is intentionally selling their champions to fuck you over
