I have been planning on doing a mass stat edit for a while, helf off until TEW13 since you can do it in seconds rather than go through each profile and I was working on using a base level of 40.
At the moment this is how the superstar quality levels look above 40
EDIT
And this is the current set up for Sex Appeal
I think the game would feel more authentic with attributes level in 5 steps, not 10 steps.
I agree that the 90s should be reserved for the best of the best, but a lot of the international talents (nakamura, tanahashi) belongs there as well.
If you like, I would try my best to make such a list for the european talent in the data.
Also, the personalities are a problem we NEED to tackle asap!
