Corner taker - good passer or good crosser?

[meis]

I've a CM with the corner specialist ability. And as you already know, crossing is not an important stat for a CM.

My question is:
A corner taker should have or rely on high passing stat or high crossing stat? I'm not quite sure on how the game engine calculates this.

Back in those days, the old version, we just spammed the ATK stats on our free kick and corner specialists.
