I play League a lot, but it's just not a lot of fun playing alone. If the people I usually play with aren't home or are asleep, I can't really enjoy League, and I don't know what else to play. I've got a lot of steam games that I've beaten or just don't enjoy, I have WoW that I don't enjoy anymore, GW2 is too casual for me, Wildstar is dead... I just don't know what else to play.
Nothing good is out right now tbh. Once Identity comes out then that will be the one I'd suggest. $15 for pre order of willing to wait until release and $30 for pre order if you want early access which should be starting next month.
Have you tried TERA?
It has shooting elements but it isn't actually a shooter. It is a life simulator.
If you want to do stuff like raiding then would you consider something like Rust, Ark or Conan? It isn't exactly MMO but you can find 200 player servers. Sometimes 500 man servers pop up.
FF14 is pretty cool and the new expansion is coming soon. Plus it's cross platform
