SMT Imagine Online.
Seconding that, one of the best F2P out there if only because the gameplay is not cookie-cutter like most of other F2Ps. The game is classless so you pretty much level up what you like using and imo it's a feature that should be in more mmos (if not all of them). And then since it's SMT you can have demons ! Demons are pretty much like a pet who follow you around and has skills and spells, you can fusion them to get stronger ones or you can negociate with wilds one in order to convice them to join you! It's kinda pokemon-ish but it's nice ! There are a lot of demons to choose from to and a ton of them are viable so you don't have to pick that one demon that surpasses all the other ones.
Otherwise.. there's Lineage 2 that went F2P lately, it's 100% free and the cash shop only has XP boosters. Though the servers are crowded as hell atm because of this so you can't expect anything above 20FPS unless your PC is a beast from hell.
Dragon Nest, Dungeon Fighter Online and Vindictus are three good ones, instanced areas with really action-y combat, feels almost like a beat'em-all in that regard, Vindictus and Dragon Nest play similarily, the first one has a more realistic artstyle and the second one is really animu. Dungeon Fighter Online was popular for a while here on B8, Pun even maxed a character ! This one has already been described above so I won't describe it myself.
