Hi there,

The recent update which doubled the bonus of ranks for monsters in server #1 was not appropriate for all users so another solution was applied.

Now it will depend on your character level - for each level after 50, units will get stronger by 1%.

This mean that, for example:
Level 1-50 players will meet the same strength monsters.
Level 60 players will fight +10% stronger monsters.
Level 100 players will fight +50% stronger monsters.

This applies both for ranked and non-ranked units. Health is not increased and remains the same for everyone.

Good luck!
