Let's link a system ostensibly about Mastery to an RNG System!
Because who says something called "Mastery" has to do with skill?...besides the dictionary
Seriously why do I need to PAY for a champion shard, and then PAY to unlock Mastery 6 & 7? Rather than...oh I don't know, just earn it through good play? And I mean just earn it. Earn!
I know some people will shoot this down and say "Oh it's only IP and Blue Essence, not like there's much else to use it for" And while I do appreciate the efforts to make Blue Essence not so much blue piss in the wind as a resource, this is just the most illogical way to do it. Same with making an IP sink, the efforts to make one is nice. But again why do we need to _buy _ Mastery 6 & 7!? Especially for how lackluster the rewards are it's just crusty fried bullshit and a massive cash grab in a flimsy disguise. People were asking for champion icons for rewards! And as usual a fantastic idea was totally ignored!
Why couldn't we just unlock 6 & 7 through skilled play? Just get so many S ranks? Riot you could have left it at that and 6 & 7 would have been just fine, great even! But no you simply can't take the most sensible course of action.
