I haven't been playing for a long, long time. Is skill decay due to infrequent use still a thing? My characters have lost most of the skills I had skilled up. If so, are there any plans to remove this nerfing feature? What is gained by decaying a players skills due to taking a break from the game or lack of frequent use? What is the logic behind such a mechanic? Why is it needed?
There is no mechanic to decay skills over time while you're not playing. Skills only are reduced as you gain other skills. If you like, you can open a help ticket and I can search database backups to check your character's skills over time to see if there's anything strange or unusual that's happened with your character.
