This is a pretty simple suggestion. I thought it would be cool if when you click decline for a party invite, there was a list of reasons you could pick from, ranging from things like: Maybe later, to I’m already in a party. It could also work as a confirmation similar to the quest confirmation. I’m always accidentally declining party invites. it’s not always an accident. So, that’s it! Tell me what you think, and if this is a dupe, I apologize!
Edit: There should also be an extra STOP SPAMMING option when someone has sent multiple requests consecutively.
