hextech crafting, when you have all champions in the game

will it be smart enough to not roll champion shards and essence for you that you cant use?

from a video ive seen, there is a random chance to roll 150 cosmetic essence. it would be nice if champion shards would be replaced by that. even if it was just a small amount like 50 in place of a champion id take it over something i cant use.

also, chests are limited to 4 a month already anyways. instead of unlocking them upon reaching mastery rank 5, which would require to play a ton of different champions for the rewards over a course of a year, it would be nice if they were unlocked every time you gained a specific amount of mastery points on a champion. (multiples of the combined points it takes to level to rank 5).

this would make the system a bit more rewarding for people who like to main a specific champion or play a smaller pool. you wouldnt feel like youre missing out if youre not trying to get every champion you own to mastery rank 5.

most people are trying a lot of champs, but end up sticking with a handfull, or maybe 10 tops.

would be nice if someone who reached 200k mastery points on nasus would get recognized the same way as someone who ranked up a ton of champs to rank 5 and then moved on to the next.

edit.: also, i read something that chests and keys can be purchased in the shop. any prices on them yet?
