Getting Champion Shards from Hextech Chests is an ethically questionable sales tactic.

Riot makes a point of promising that they don't use some of the unethical methods that 'pay to play' or 'freemium' games use to make money off of their communities.

However, getting free currency in exchange for real-life currency, like receiving blue essence from a chest purchased with Riot Points, is at best disingenuous and at worst deliberately predatory.

To be ideologically consistent all blue essence must be earned for free and used to unlock free content only, while all orange essence unlocks paid content only.

This change would prove beyond any doubt that Riot prioritizes protecting their community over maximizing profits.
