A Discussion about Hextech chests and key fragments

Hi, I really like the Hextech system Riot has implemented or rather the chance to get free skins. Of course they dont want someone to farm boxes and so they restricted the ways they can be obtained. You know the details by now: 1 per champ, only with S- or higher, and only one box per week.

Now, you could argue that it's hard enough to get an S- on so many champions and that you should just get a box whenever you score that well for the first time on a champ, but that might be a little too generous. It doesnt really matter.

What I dont understand in all of this, are the key fragments. Like I described above: The ways to get a box are already very limited, BUT they have very clear rules and are fair. The key fragments on the other hand are just randomly dropped grindloot that puts another hurdle on the Hextech system and I really dont get why they are there in the first place?! Right now the keys mostly confuse people in regardss to why they dont get any. It's random for once and riot is meddling with the droprates over the month or maybe regarding other factors as well, which is intransparent and therefore rather frustrating for players.

Imagine there were NO keys and you can just open your box when you get it. This would be a very simple but good change of life improvement for the Hextech system. After all, the keys have no effect on how many boxes you get, they only delay you from opening them.
