There was MASSIVE and fundamental changes to WoW classic that basically broke the entire experience. I'm talking about layers and huge overblown servers. That completely ruins the entire feel and was the reason I couldn't play WoW classic. Fighting for mob kills, or players self-organizing for killing them is a MAJOR MASSIVE appeal of vanilla. Its called community. By adding layers, it takes away any reason for people to actually talk to each other which ruins everything. With server pop caps much higher than vanilla, it makes everyone feel totally anonymous. That's a HUGE change. You should have vanilla-style servers with smaller pops so that you get to know everyone.
Playing vanilla is ALL about community. I look at WoW classic and its a joke with these massive changes that destroy community.
We need WoW classic with NO changes.
