The way Warframe loot tables work, when something drops there is about a 20% chance to get an uncommon and a 2% chance to get rare.

Problem is, this table is very crowded. The chance to get a specific uncommon Arcane here is only 1 in 40, and a rare is 1 in 350.

Nightmare mode now rewards guaranteed rares and people are starting to beat it more often, but that doesn't help with an uncommon.
