You think its a bad thing that 95% of the people who have played wow over the last 17 years no longer play it? I think thats an astonishing retention rate over such a long period. Its also an entirely useless stat, and you know that. What is important is each expansions player retention - the fact some kid tried wow in 2004 and said "not for me" and no longer played it is in absolutely no way relevant to Shadowlands.
