Now, let's roll this around to what's actually being discussed. The DM comes to you and tells you, you have to do X because the dragons are telling you to do X. If you don't do X, you will no longer be a sorcerer.
After all, you "chose" to have this patron relationship. It's perfectly acceptable, according to you, for the DM to use that relationship. So, the DM exercises his or her power and tells you that you must do X or lose your class.
How are you feeling? No problems? Not a qualm? Perfectly acceptable DM practice?
i find it amazing how much you keep showng and even spotlighting this lack of comprehension about what was actually said.
Asi i said there and in other posts, at the point there was a warlock-patron offer on the table, myself and the Gm would have discussed it and came to an agreement or not came to an agreement.
Just to make sure this is clear - we both have to agree on the details or no class/multi-class warlock for **either** of us to enjoy (use) in game.
Now, of course since i am more sentient than an unawakened shrubbery, things like "can i lose the class, can i lose certain abilities, how much warning advance punishment staging, etc and in essence how this will play out etc will be part of that discussion.
Obviously, the Gm can put as part of his proposal "if abc then ytou can "lose class" (whatever that means in practice - we would be clear) etc. if i find it unacceptable, then i counter, or refuse - you know - n-e-g-o-t-i-a-t-e - some might see that as the player having input etc.
Repeating again for those just catching up - if we do not reach an agreement there is not multiclass no patron for either of us to enjoy (use).
BTW that also means the GM doesn't tell me what to do, the patron might threaten and have the leverage we agreed on etc. but within the player-gm bounds we set.
After that, assuming we reached an agreement, we go forward and both i and the Gm play the game and have fun...
Now obviously at some later time a Gm can break that agreement - step outside the player-GM deal - and that brings us not to warlock-patron but table-gm-players discussions.
it seems at times you may have a difficulty differentiating between THE GM and his NPCS and the PLAYER and his PC.
But regardless, the simplest answer to your overly simplistic query is **IF I HAD AGREED THAT WAS WITHIN THE SCOPE OF THE GM TO DO WITH THE PATRON** then "yes" i would go along with it. After all, i agreed to it and i keep my word to my fellow players about how i will play the game.
After all, its not like i would want to choose and agree to something with drawbacks and then be a wuss or something when those drawbacks show up. Or come to the table to negotiate with the belief that what i say goes and its a one way street cuz somehow i get to define how NPCs act to my character.
