Hello!
Today's Nation War Event showed that the strength of the kingdoms is already at a similar level (Jinno, I'm still waiting for you.) I think the handicap could increase with every win. Of course, it resets after a defeat.
-- current handicap value is 30% --
Example: Jinno wins the Nation War.
- 1st Handicap 5%
- 2nd Handicap 10%
- 3rd Handicap 20%
...And so on until 100%
Have a nice day,
Sheen.
