hi gamer people I'm in need of your help

I want to find a game that will fill up some of my free time. Something with these qualities: enjoyable, multiplayer, easy to learn but hard to master, good customization (or many characters to choose from). I don't necessarily want it to be a moba because I'm not really good at mobas and I don't really want to be good at mobas. I just need something that I can enjoy and also put effort into to get better at & advance in. For example something with Torchlight qualities. so ya, if you could suggest some games 4 me that would be great.
