This has been a topic on the back burner for some time. 'Worgen' is a term used by WOW and we don't allow officially licensed this and that in the game.
We currently have no active Worgen players, so now is perfect time to rename them. Rather than come up with something altogether original, I am going to name them 'Warven'. I'll be doing a lot of CTRL + H to change up the name here and there, but will not be altering any adventuring threads.
However, I am also going to alter their design a little. We have Garou and Worgen and really, it's just a hair confusing. Much like Cathians, cat hatchlings, panther humanoids and someone mentioning giant cat type people like feline Worgen (no thanks!). Worgen won't be the archetypal wolf - anthro but rather, will be part bear as well. Big, furry and deadly, a real mix and far more original. I had planned on doing this some time ago, which may mean extending their Lore.
Oh, and for anyone who like the idea of giant cat people (we don't need more cat people!), ignore this awesome pic.
