The thing I like most about Epoch is it's claims to be Classic+. Every private server claims to be Classic+ in one way or another, but there's a huge difference.
While the lagfests and cyrillic, alien languages plague nearly all popular private servers, they use Classic+ as an advertisement. Not Epoch. Epoch uses Classic+ as a homage to what they've completely revamped and improved upon in a way that the original author could never accomplish.
It's objectively and literally a tip of the fedora at the original WoW team while saying "We'll take it from here." That's not funserver, that's betterserver. That's Epoch Classic+.
