There are still some private servers with huge population but I see less and less options out there, most players just want to play the old and boring pre-re or classic server. Renewal brought so much new content, quests, instances, mechanics but most players didn't even try these features before going back to something they already knew. The innovation is also on decline, most servers just have the same basic set of features that you can find on almost EVERY other server, a few years ago you would see servers with a reset system or a low rate with a super high level cap, a ton of events, custom items, even custom classes and skills, it was super fun to enjoy a brand new world inside of a world you already knew. The servers just got more and more boring, today it's super hard to find a server that I can play for more than 2-3 weeks.

I wanted to say is: a few years ago innovation and different features were something that most players wanted, but today I mostly see the "different is worse" kind of player, it's sad and super boring.
