Multiplayer question, ples help

Hey guys.

I was wondering if there was a system or a way to have servers like World of Warcraft does, if that makes any sense?! Any suggestions are much appreciated.

The idea behind my game is i’m going to be working on is a mix of MOBA and MMO with top down kit like Dota 2 has.

Edit: I guess i’m mainly looking forsuggestions to get to a starting point. Maybe a link to mmo starter kits. Yes I realize it has a lot behind it and stepping into game creating as a beginner a MMO may be out of reach, but im hoping for suggestions to getting started or kits i can implement into it.

No, there isn’t a pre-built “system like WoW”;
Tip: aim lower.
