This chem stuff is far too in-depth for me.

Personally ill just make teams with full chem as i always do, apply chem styles and reap the benefits.   I dont really see the need or point in going in to this level of depth on it.  Its just chemistry 

It's interesting, because you have some numeric advantage of Chem 10 vs 9 or 8, for example. And with the Chem bonus you can get (Manager + Loyalty), it's now easier to have an out of position player with adequate chem.

For what I'm seeing, having a, for example, max chem or close LW Hazard playing as RW whould definitely be doable or at least, you'd have some relative number to see where the chem penalty is going. It might open interesting possibilities, specially with formations out of the way.
