I actually downloaded and played a bit, used Evie since the scythe looked epic and the evasion skill blink fitted my evasive playstyle more :b I recommend at least trying it out, there has been 2 new charaters added and 1 more coming from what I just searched since the time I played it. One of the bad points is that it will be grinding the same maps for some time to actually progress and get what you want (equipment and other items) but the multiplayer makes these parts more enjoyable~
The dungeons can be a bit too straightforward but usually there is a boss fight in the end giving more excitement to the "Go to point b. from point a." I didn't get to fight the bigger and challenging bosses, other than a big ass polar bear

I didn't have time for the game back then, but now I might pick it up again :b
The play mechanics resemble TERA a bit, meaning you need to aim your attacks yourself instead of just spamming buttons to cast autotargeted skills, so Vindictus can be a new experience to people (it was to me) It's not open world, but it still works. And you can go solo if you don't like teamplay, but I recommend going on a quest with a party since it will be more fun
