If you've played Vindictus then you will be familiar with the story-driven quests and the real-time dungeon combat. Currently there are four classes you can play as, as well as two class specializations to choose from at level 15.
In the Open Beta the character level is capped at 24 and there is currently an Open Beta event that rewards you for each time you level up as well as every hour you are logged in per day.
Classes are gender locked so this can be a bit of a problem if you HAVE to play as a certain gender.
Current classes and their genders:
Warrior: Male
Cleric: Male
Archer: Female
Sorceress: Female
If you're interested in fast, fluid, real-time combat and enjoy a great storyline (with movie cut scenes!) then I suggest you check this game out.
Edit: If you're on the Elena - West server, look me up in-game! My character name is Snotnose and I'm a level 12 Cleric soon-to-be Priest.
