My best guess is, many years ago, Guild Wars 1 and TERA had a secret child, which they forgot about. Vindictus is a hub-based online action combat RPG with some MMO elements, it's a fantasy Warframe with none of the polish. It's not a bad game, it's just not a fantastic one either, it's a relationship good enough to stay in, but bad enough to never quite be as happy as you know you could be.
