Pure RNG is the worst thing ever.

[Heskett]

So here's what you do. You have that 10% drop rate (though in XIV in some cases it's more like 2%). You also have a token drop. After collecting a certain number of tokens (in your example 100, but that's a bit much IMO), you can trade it for the item if RNG hates you.

See, XIV has over 4 million accounts, probably around 500k active subscribers. Even if there's only a 0.1% of having that really terrible luck, that's still hundreds of people you're writing off.

I think it's anti-climatic and makes the reward less well... rewarding. I'm all for RNG just for that moment where you go "omg finally" or "yaaaas".
