The point of Hextech Crafting was a way to get free content from playing the game well.

Then why the hell does it cost between $250-500 to get the Exclusive Hextech Skins? (Hextech Annie or Soulstealer Vayne) It takes 10 gemstones to craft Hextech Annie Or Soulstealer Vayne ( <---- Releasing next patch).

Which are INSANELY rare so I almost 100% assure you that no f2p player will EVER get the skin (unless you get the shard which is even rarer)
