When v9.1.5, tons of people will switch covenant, simply because it becomes so easy, and we have all reached max Renown.
But some people have ofc already switched, so it should be possible to answer anyway:
What happens to the "neutral" (in lack of a better word) companions, such as Meatball, Croman etc?
Will be start our new covenant with 10ish level 60s? Will we have to find them in Borghast again?
