Is the Hextech Crafting exclusive skins really gonna be a thing?

Maybe it's just me, but I really dislike the idea of having to rely on luck to get the skins I want.

To me, having a cool skin really makes a difference in how fun it is to play a champion, and it's very exciting whenever a new skin is revealed for a champion that I play. I really like the idea of being able to craft skins via shards, because it's always nice to get some free skins, whether you pay or not.

But now theres already two skins Hextech Annie and Soulstealer Vayne (on PBE) which are exclusive to Hextech Crafting, making it completely random whether you get the skin or not. And I find this trend really disturbing. I'd be really pissed if my favorite character just got the skin, then to find out that it's Hextech Crafting exclusive. If I'm lucky I get it in the next chest, but if not, then I may never get it. It's like dangling a carrot in the face of someone, but with no clear way to get it, other than having luck on your side.

If there absolutely has to be skins that you can only get in crafting, make them timed exclusives, and then after 3-6 months, make them available to buy or something.
