then do as you say. as soon as we reach level 100 revert to level 50 and put stars or color the name as achievement to reach 100.
the default is black color, 1st time reach 100 bronze color, 2nd time silver, 3rd time gold.
or put stars on top of your name or decorate the player profile on friends list whatsoever.
other game did this for the one who have reach milestones or achievement etc
edited: also when revert just throw the team into new server. hate facing same team even after you got revert after reach100. basically that's the same.
yeah you can manipulate % in order not to face same team, but i hate doing that.
i only did that to reach 10trebles and only sell unwanted players now because winning trebles without fight is boring. might as well just play single player offline football manager.
