Key fragment droprate is very low
I recently came back to LoL after a long break, and started collecting the key fragments and chests back in July.
My complaint is that the key fragment drop rate is much less than what is required to open the chests I've earned. The rate of chests is tightly controlled - 4 per month. It would make sense to me to at least get enough fragments to open the chests I'm able to earn. I understand that the drop rate is not linear, but in the past month, I've gotten 5 key fragments and 4 chests.
Even if I'm a little on the low side for key fragment drops and the intended rate is 6 per month, I'll only be able to open half of the chests I earn. I feel that the imbalance between chest and key drop rate results in a very annoying experience. I want to collect more chests, but without keys, it feels pointless.
This isn't about money - I'll use money to buy the skins I want. The chest/key system is a little collecting minigame that can result in me getting a champion or skin I'd never spend IP or RP for. Right now, each S rating feels great for granting me a new chest, but it's disappointing that the chests keep piling up with no way to open them.
