If this idea was changed to punish managers (somehow , I know there is a very minor punishment now which really is a pittance once you get past level 10) who dont even log in each day then you might get some traction with people. The fact of the matter is these are the people who dont care and maybe should have sanctions against them and not those who do log in every day , train players etc but for whatever reason cant attend 50% or more of games. Myself , due to timezones the best I can do is maybe 60%. From that 60% we lose maybe 10-15% due to work and other rl issues so I am now down to or past the 50% threshold that you suggest but I log in each day , collect my crap , train my players , study opposition etc all of which takes over 3 hours every day ( 5 teams currently) which is probably more of a daily time investment than than most I would guess. Besides my teams seem to do pretty well without me watching every game , maybe they would do better if I watched all the time , maybe not as suggested by other posters.

Now I am really wondering what is your problem , what caused you to post this idea in the first place. It seems you didnt think it through so I might assume you lost to a team that had an absent manager and in a fit of pique started this thread. In that case I can understand your frustration and hence this thread.
