(posted part of this in help forum, but seems relevant here as well with the GS speculation.)
Just had a player that didn't play a single minute all season increase in game shape...
& another that played 58 minutes fall close to 2 levels of GS? (DMI was cut in half, despite receiving full training & a skill pop)
But even from this week alone.... another guy with 50 some minutes & full training had his DMI fall by 60%. None of my players receiving training popped in GS, & none have ever gotten a visible cross-training pop either.
So as arbitrary as GS seems to be, how can anyone know if GS is one of the things receiving cross-training or not? Also, seeing as how GS isn't an actual "skill", & is listed separate (under age / height / potential)... idk. Just makes it less probable in my mind that the 10% goes there.
