I had an MC with corner special ability last year (2015). He was the first option for taking corners on the right hand side. He obtained 10 assist in one season, mostly from corners. But, that was on the old version, where skills points are distributed throughout the attack section most likely randomly; so, he had good crossing skills. On the new version, MCs with corner special ability will need additional training for crossing skills. Crossing is not an important skill for MCs. So, it is better to avoid that special ability on MCs. For the case of DL or DR, it is the creativity that is lacking.

I prefer the new system though as it allows the user to train a player for specific skills in a particular section rather than assigning skill points randomly in a section.
