No, I think most of us will be pretty much done after WotLK. Maybe join a fresh Classic server. Or maybe fresh TBC to see how it will be different from transfer TBC.
Was really hyped for Classic but at this point I think its time to finally let WoW die. What they did with Classic could be called desecration and is worse than any private server in the last 10 years. But as long there is money to make Activision will have legacy servers up to BfA.
