It’s a hot topic for sure but you should report a bug each time you come across it. Of course, if you do it every 5 minutes that might be a bit overkill but generally speaking you should hopefully not be running into the same bug every 5 minutes.
It’s also important to put in as many details as you can while being concise. How can the developers reproduce the bug? What does it affect? and so on. Additionally, if the bug is so game breaking that you can no longer login or play your character, that’s where our support team can come in to help.
While they might not be able to fix the bug, they can at least look into the character being unplayable and work on fixing that. So if its gamebreaking, make a ticket. Otherwise, use the ingame bug report feature as often as you desire
