As a title mentioned im suggesting that kyubi level based on number player participate, since we got 5 servers merge today kyubi only last 7 mins that mean less coins player gets.
here for example the kind of rule for kyubi level
if player>50 then kyubi level 25 else like our current system kyubi at level 18
or
if player>50 and player with 30k power > 20 then kyubi level 30
else if player>50 and player with 30k power > 10 then kyubi level 20
etc
thanks for the merge anyway its fun to have more player
