The thing is though that you don't have to buy everything. if you are just single players guy you only want the single player stuff. If your into the multiplayer all you have to worry about are the commanders. Skins and faceplates are just extra stuff if you like them and can be completely ignored if you like.
The idea that they are trying to do is add new content to a game over time instead of an expansion, which takes a long time and a lot of money to do. Since none of the stuff is mandatory for you to buy you can just buy what you want, the meta game however can change all the time.
One of the biggest problem that rts's have is that once a game gets older it gets stale because everything is figured out and it is just execution. With commanders this will never happen, could it be done a little better sure, but this has also never been done before in an rts.
I have no problem with all the other DLC but multiplayer commanders is what kills it for me. If all the commanders would be include in the CE, I would upgrade for the CE.
I even purchased a skin and will probably buy some more but I don't agree for multilayer commanders. I really wonder if it's worth it for them I mean how much money did they really make with this vs. the frustration it brought to players.
