What incentive do you need to stay?

[Synrin]

Now imagine you are not even joining that PF for yourself but for a friend.

If things go wrong and they will... Do you suck it up? No, I am vocal about what needs to be done.
Do you speak up when someone is "doing it wrong"? If so, when and how do you approach them? Refer to the answer above; I will try to explain nicely and in detail in order to help out the entire group.
Maybe you have a mental illness and just want to finish what you started? It's a game, not getting a perfect group is part of any game, and you can only make the best out of it.

Do you help new players progress through coil/EX/Gordias and if yes why? I play because it is a game and it is meant to be played. If I feel like doing something, I will do it. There is always some sort of a reward included, so it can't be that bad.

On the other hand, what really grinds my gears is when people are being bad ON PURPOSE. Fuck them.
EDIT Then I am even ready to leave. Sometimes it just won't work out and turns into a waste of time. What is waste of time? Playing a game and not enjoying it.
Although 'waste of time' is subjective.
