Thank you for the warm welcome @Saviour!
To be honest, most private servers are way to custom for my taste, I just like leveling and playing the end game content (level 110 in this case).
There are also "Blizzlike" servers, but those have many broken quests and many other things don't work either.
About Blizzard bringing back the old classic servers, I'm very excited about that as I have never been able to play and experience that time.
I started playing during the Wrath of the Lich King expansions, so to be able to play like it was back in the day, would be pretty awesome!
Many people hate Blizzard for their actions of taking down private servers because people pay and play alot on these private servers.
So when Blizzard is taking it down, you kinda wasted your money and time into something that maybe only existed for a few years.
