I played the Taiwanese version for a few years. Gameplay of Vindictus is fun, yet Vindictus contains some bugs (hit any enemy critically but sometimes cannot use Gliding Fury/Lightning fury then, hit any enemy but no hit is confirmed by the system) which make Sword/Spear Lann disadvantaged.
Moreover, the game's system of building a character is tiresome that drains my mental stamina. I tried farming the rare raw materials like scrolls, sealed power, for a few hours every day, yet I rarely got the thing(s) I wanted. Although now the developer adds Partholon Vanguard, which allows players to get random (some rare) materials without needing to fight in order to get some materials, to Vindictus, I have to go online to use the function, and I had to grow my other characters which I don't like to use to get more materials at a time. It's no problem that I have to take a bit of time to build my character. It's a problem that I have to take so much time to build my character and have to play this game like a worker.
