[Module] Legendary Potential Rarity

It's always been the case that you have a small chance of obtaining a potential line for a higher rarity, at a low success rate.
The lines don't decide the rarity. The rarity decides the highest likelyhood of the lines.... with a very small likelyhood of higher rarity lines showing up.

Yes, but have you ever seen an item with 6% on the first line thats rare?
No, you haven't, because getting 6% on the first line of a rare item CAUSES it to go epic.
