MMO that will suck me in?

The two MMO's that I've been addicted to simultaneously for a while now are Vindictus and Tera, since I prefer the action-combat system.

If anyone here plays Vindictus [East] or Tera [Ascension Valley], let me know! <3

Try Realm Of The Mad God

If u like Diablo (or similar games), try Path of Exile. It has huuuge skill tree so you can really customize your character by your desires. If you are looking for a "normal" mmorpg like WoW or GW2, try TERA. It's now free and has awsome combat system and races. I stopped playing it because I like playing as a tank. But in tera tanks have a lance :( ugh. Vindictus is also very good but is missing an open world (someone may like it because you just log in and go dungeon or pvp directly). It's fun if you play with a friend. I stopped because my friend was not playing anymore :(.
Currently I am not playing any MMO but soon there should be available 'Black desert online' and 'Blade and soul'. I am looking forward to try them.
Sorry if I mentioned games that other people already posted. Was too lazy to read all the comments :).
