Skins sets still not skins sets

So, a couple of weeks ago I was wondering why the store sell a “pack” with skins that only fit for a couple weapons. And today they give me the answer.
They have no intentions to sell a full pack, they ripped off the set in two, and three parts each.

One for riffles, another for power and even the pistols are sell by them self’s.

This is beyond ridiculous, what’s the point of “buy exactly what you want” if this is going to be the method?

9 buck for 5 weapons
Another 9 for another 5
5 bucks! Only for the lancer!
Another 5b for talon!!!
