It’s absolutely broken. If you lose it on a character there’s a chance it’ll never come back. If you don’t use the forum daily it’s not even worth grinding for because maintaining it is a hassle ![:pensive:](https://d38bqls1q93fod.cloudfront.net/en/wow/images/emoji/twitter/pensive.png?v=6" ":pensive:")
Best thing you can do is start over your progress on a new character. TL3 is granted to your forum character, not your account, so any progress is completely unhindered by anything that happened on another character you used to post.
