A particularly well-rounded player will continue to receive cross-training but will see a much lower reduction in primary skill training, while a particularly one-dimensional player will see a larger loss.
In the past well-rounded players benefited when training one of their higher trained skills by having with less drag from higher, well rounded secondary skills. This seems to be static or accentuated within the new system.
