DLC is bewildering

Leaving aside DLC as such, pay to win and so on.

Is it just me or is it really hard to figure out the DLC structure?

I preordered, so I got some commanders, and recently got the case blue expansion also for free.

I can also buy the digital collectors edition, and an upgrade to same. I've no idea if this might be a good purchase since the actual content is so vague. To even see the digital collectors edition i have to add it to my cart and then enter it.

This includes a bunch of commanders (10) but which ones exactly? If i upgraded would I get commanders i don't yet have?

The Commander list is a mile long, and I've already got some of them, yet i can only see which if I enter each individual item.

I would really some more details in the store on all this and some "show only non-owned items" option.

Better yet I'd like some sort of group purchase option for commanders that would give me the ones I don't have.

I'm a MP player only, so all I really care about are the commanders. If there was a discounted "subscription" for the commanders i would buy it just to save the headache of evaluating each individual commander to see if I have it or want it...

The store front was altered, prior to week beginning 9/10 it was listed in the description if you did already own a DLC, no drilling down or adding to basket needed.

All your preorder content was taken from the DCE content, so subtract that & then decide if you want it. If you just want commanders its definately not worth it. But the list is on the games main store page, check it out & decide for yourself
