The debuff itself has been part of the system almost since the Vote to Kick system was introduced. It became an unfortunate necessity as certain players would urge the group, by request or by being a nuisance, to vote them out in order to avoid receiving a deserter debuff.
However, I’m afraid Customer Support has no involvement in the development of the game or the related systems, Pompom. If you have feedback for our Game Developers it is best to submit it through the in-game Submit a Suggestion option found in the main menu in-game under the Support option, or by posting in one of the related Community Forums. Dungeons, Raids & Scenarios would be best in this case.
