I have no idea how big the team is, I have not seen any posts about it, so I am not sure where you got the number 10 from. I am happy that Classic is coming out, but unlike most people I realise most will play it for a month or two and move on.
Yes, salt all the way, especially since I said two times now that I am going to play it and enjoy it, but dont see myself staying for the long run as iv done it once before and in my eyes its enough.
BFA is crap, thats 100% true, and I fear no one has bashed it more than me, but even as crappy as it is I would prefer to continue here as I dont know what to expect in the future, where as Classic? Every single detail is known and that fact is kind of draining me before the game even launches.
But trust me, buddy, if you enjoy it and plan on playing it all the way while telling yourself its the same experience I am super happy and hope you have fun !
