Have you heard of Nexus Clash? I've been playing it for around a month and it's fun.It's essentially a free to play text browser based PvP MMO that you can play in any browser. Think something like Urban Dead except it's a fantasy game.
It's got a deep class system based on morality (evil, good or neutral) where you can become an angel, a demon or a superhuman based on what alignment you are. Some classes such as lich (a neutral mage class) allows you to build undead armies from players you have killed, while others such as corrupters (evil class) can corrupt players or players minions and pets. There's a plethora of classes such as revenant (basically a creature of the night, have skills that allow you to track players who have killed you or people you know, or eternal soldiers - masters of any sort of human combat be it guns, hand to hand or melee, to archangels - high ranking angels that can command other angels to some degree. (Here is a list of all the classes. https://wiki.nexusclash.com/wiki/Classes
A big thing is after a few years one side of the game (either evil,Neutral or good) wins the game and the game resets with the winning side helping to structure the new game map.
If you do play, I highly suggest reading a new player guidehttps://wiki.nexusclash.com/wiki/New_Player_Guide
