Patch 1.19 will see battle regimens disabled due to changes to the battle system and the claiming system making them unusable. This will be disappointing to players who like to use them in dungeons for completing the speed objectives. However the good news is that they will be improved and return in a later patch along with the job system.

Also being removed in patch 1.19 is the physical levels. Currently players level up their class as well as a physical level which is used across all classes. Players can set attribute points from their physical level to improve their class levels. In 1.19 the physical levels are going and the ability to set your own stats will also be gone. This means no more 1000 clicks to switch from a disciple of war to disciple of magic! However it does mean loss of freedom with this aspect of the game. The good news is that the ability to customise stats will also be returning in a later patch. But for now they will be automatically set. The full details on this is below:

"Patch 1.19 will see the abolition of physical levels.

Along with this change, the following adjustments will be made:

Abolition of Attribute and Element Points

Attribute and element points will be abolished, and character development will be automated based on class level. A system whereby players can voluntarily allocate attribute points to each class will be implemented in patch 1.20 or later, along with class balance adjustments.

Introduction of Automated Character Development

Automated character development will be implemented in patch 1.19, and will entail the following changes:

The growth curve will be revised, with each gain in level to be accompanied by greater increases in attributes.
Attributes will be made to have greater impact.
The impact of attributes will decrease as players gain in level; however, the benefits granted by gear will be increased.
Player accuracy will be increased slightly.
Race-based differences will be limited to the starting attributes.
Revisions to Terminology

The following in-game terms will be renamed.

Skill points -> Experience points
Rank -> Level"
