Farming boss for relics

[MonsterOfMyOwn]

I've started playing a few monthes ago, and played as a mid-core dedicated player. My experience so far is that appart for getting Frost and Rhino in early game, I never "farmed" bosses, and to be honest it was faster / more rewarding to get Primed version of frames while doing other activities. (Hierarchon, Hydron, etc)

I would really like that farming corresponding bosses was an optional way to get relics that have chances to drop primed version of the warframe.
And example would be a Jackal available at several level, having a reasonnable chance to drop Lith at lvl 15, Meso at 25, Neo at 35, and Axi at 45.
(chances should be at least 25% to be consistent with "rotations")

These fights would be obviously available when the prime frames are unvaulted
