Why is it so hard to get these skins

Ya ur right

It won't be expensive if u become old players you'll get it eventually

I got both of them in 3 months easy skins to get they really don't need to lower prices it's fair for such high detail skins

Correct me if I'm wrong, but I believe the price for these might have actually come down. I want to say I remember the Kazama skin being more when I first started playing. The best thing to do, is wait and dont buy anything else with glory points, just let them stack up until you can buy both. All the other skins are a breeze to get.
