So I recently made a post talking about how difficult of a time I was having trying to complete tall tales while playing solo. And while discussing it had an absolutely amazing idea that I think would greatly improve the experience of playing tall tales in Sea Of Thieves for everyone!
So if you've ever played GTA Online you would be very familiar with the "passive mode" that peaceful players are able to use to avoid being attacked and griefed by toxic players. Well I think a very similar system should be added to Sea Of Thieves to make doing tall tales safer. So when you start a tall tale in SOT I think that you and your crew and your ship should enter a "passive mode" where any emissary status is removed (basically the game forcefully lowers your flag for you) and your ship basically becomes semi transparent to other players (and other players become semi transparent to you) and the same for loot. Basically you and your ship can not interact with any other players or loot and no other players or loot can interact with your ship and any loot already on your ship would phase through it and go into the water underneath your ship. This would make it so that grade 5 reaper ships can't exploit the pirate's life tall tales to session hop and vise versa.
And once you complete the tall tale your ship and crew would immediately be removed from passive mode (unless inside of another players ship or person in which case once one of you moves the passive mode effect would be removed so that ships can't instantly be destroyed or broken by suddenly becoming stuck inside another ship)
This wouldn't hurt the playability of the game in any way and would be a great way to prevent players from being griefed or constantly setback while trying to do tall tales
