Lineage II is getting a bit long in the tooth these days, but the game still has a dedicated playerbase and still looks excellent. It's also feature-heavy in the way that only long-running games can be, complete with the fan-loved feature of sub-classes. Having an "extra" class on top of a character's main class is almost universally liked in every game that features it. Of course, it can feel a bit odd when you realize that the secondary class is more fun than the main class, leaving players with the question of what to do. Thanks to the newly-introduced Subclass Separation Service, the answer is now "play that class."
Not only does the new service free the subclass from you old character, allowing you to potentially choose a different one, it creates a new character of that class at the same level the subclass had reached. That means that it's ready to go as a main class right away, and without the burden of low-level questing. While not for everyone, there are no doubt several Lineage II players who can find quite good use for this new feature. (Or this feature helpfully adapted from Tabula Rasa, whichever you prefer.)
