Why? Why is there no sure way of getting an item from the crate for a high amount of marks rather than be subjected to yet another RNG mechanic? I have close to 4000 marks and granted 87 do not appear to be a lot in the grand scheme of things but 1 infuser is a joke. The least you can do is to give at least 5 or 10 infusers for that much. I'd rather have two options here, either try your luck and hope to get an item you want or grind until you have enough marks to buy the item you want. Make it 500 or 1000 marks and give the player an incentrive to grind... Same logic applies to armor patterns.
