the problem is, that when you rush out to get the new pes version, you are pretty much in a hurry to get you ML going.. but first you need to play a shit load of stupid 5 min matches on 2 star just to get enough pes points to unluck "match play teams" and maybe even increased starting points (goes up to 50000, you know).. so yeah! it is damn silly to have to wait getting your ML going until you - on top of all that - also have to pile points up in order to unlock 6 stars as this might just as well be done whilst playing..! having said that, I do believe it is a bug, as - yes! - this is how it was done in pes4..
