Thats a sad thing, mate. But: Another time - another luck, I'd say.
I was shocked, as I read so many times here from experienced managers, that they don't care much about condition, even a mod said, 80% is really okay to start a match (I still cant get it, so I have enough players for 2 squads, rotating them, even worry if anyone has like 95%, its low for me LOL).
I probably still overvalue condition. Noone knows ecactly, but I also cant believe, that those factors have absolutely no influence, I mean that would be very insane from developers, I dont expect them as totally crazy.
I think, cond, morale, bonus etc play a LITTLE role, maybe 1% each or 10, who knows. But seems like presence, condi etc are alltogether not game deciding, its a bunch of factors.
Its not realistic for sure, if the team has no training but tired after a game and wins, but otherwise only hardcore players could have success, I mean not everyone can attend 2-4 games a day at special times.
