Class System

In holic online you have a very good class system. You can have a main class and a Sub class. This mean you choose a class when you first start the game off. Once you hit lvl 10 you can choose a second class to be you sub class.
In the start of the game there is a skill "Class Revolving" that allows you to switch classes so you don't have to worry about learning that ,and it takes away absolutely no mana or mp.
There is no penalty for switching between two classes and players will be able to swich from one class to another to use combination of skill to form an optimal combat strategy.
Subclass gets to have double exp. That is as long as its lower lvl than the main class. If it becomes higher level then the main class gets to gain double exp. The other thing about this class system is if you dont like your subclass you can change it any time to one of the other classes while still being able to keep all of the things from the old subclass. Then you can go back to it at anytime and continue where you left off. The other great thing is all the classes also have job advancements.
