No, I think it is unfair to give an advantage to clubs that did early business in the transfer window. Just because they did their deals quicker than another club that shouldn't mean they get an advantage. When the transfer window shuts it will be fair but until then it is unfair to use it as its easier to achieve success with some clubs than it is without Marshalls database.
but it makes it unrealistic and either way if you choose to be Man Utd, Chelsea, Man City etc one of them you should be able to win the league anyway on either database so it doesnt matter if you use it or not how is it unfair ? but i would use it as i find the game unrealistic and not up to date
On that basis you would start a new game every day? As there are new transfers every day. Its also not that realistic as your playing with half updated squads because there is still a month left, it can not be realistic as they are not going to be the real squads those teams will go into the season with.
