where it says
Character development
There will be a single character system, a character will not have a type like at present. A single character can be used for any of the three types of game play; PvE, World PvP and Structured PvP.
The level cap of 20 will be raised, no maximum level has been given and it has been suggested that there may be no maximum.
The skill system will be modified. There will be fewer, less complex skills which may behave differently in different situations, such as if the character is jumping or is surrounded by monsters.
Marriages and auction houses may be implemented.
