I don't play tabletop games anymore. Haven't played in years. I played the original box set and first edition, which was Advanced Dungeons and Dragons, and then I played second edition, and for a while I tried third/threepointfive. Fourth was where I just stopped.
But if I did, I would certainly only play with folks who were on the same page.
D&D tabled are generally brought on the same page by the DM...DM ruling is final. So unless you have someone who wants to argue with the DM too much it's not really an issue. But really, depending on how your DM plays your patron you generally can ask for clarification...for example if your warlock just signed to trade his soul for power the patron shouldn't be making demands or getting involved unless the warlock is taking action that could lead to nullification of the pact...like trying to achieve godhood. That kind of stuff. It could also be worth discussing this stuff a bit when you first create the character and see where the DM's thinking is at.
