you never did say what you were playing before so we cant quite make a recommendation based on what you have already experienced.
Anyhow if you want mmorpgs then why not try Tera or Raiderz? (both are good action-mmorpgs, meaning you actually need reaction and coordination in these games)
If those are not to your liking then why not try a room based battle mmo like world of tanks or war thunder thats on your background.
In terms of shooters you could play Planetside 2 the sucessor to the first true mmofps (its not room based but rather a gigantic global war)
you could also try out wakfu or atlantica if you like turn based combat (there are more but most are too old to talk about or are browser based)
and yes.... the guy above me is right... this should go to the mmo requests sub-forum
