Relic Armor

I have 3/4 of the old just plain relic armor. I've found out where the relic guardian spawns for leggings and so far I've picked up air and water leggings. Do the plain relic armor pieces still drop?

 

Each piece has about a 20% chance to drop from the relic guardians, and each relic guardian can drop all types of pieces. These are all individual chances, so you can get more than one piece of armor per kill if you're lucky. And yes, the rainbow relic armor still definitely exists in the drop pool.
