I should have known that the reason this thread is so long is because of 'logical' people attempting to frame their selfish behavior as completely rational and untainted by the impurity of emotion because they cherry-pick some 'logic facts'. It's not about whether you can do it or not, it's about whether you should and I think you'll find that a lot of people don't think you should! Which is why a companion roll is necessary, you can't be trusted to use the 'need' option like everyone else uses it.
Your defense, lol, is of course that you believe everyone else has the right to be just as selfish.
Keep on condescending though! It's easy to make a simple argument when you ignore all of the variables that don't immediately concern you.
But hey lets look at this logically, you're rolling 'need' on something that only benefits yourself. It will not come into play in a group, you don't have your companion out. When a player character receives loot, it will actually factor into the success of future groups and that benefits everyone. Not just you. Maybe that's why people get upset and call you selfish? Because you're selfish.
