Please rework Tribute, its both anti-synergistic(accuracy debuff and then damage reflect without any tankyness to speak of... what?) and not useful(25% slow is, for all intents and purposes, absolutely useless, especially given its horrid base range; 75% more damage to companions is almost as useless because their AI is bad and aside from a select few sentinel weapons, they never do enough damage to justify a damage build).
The only even semi-useful thing in the kit is that accuracy debuff, and even that is mediocre as-is.
And please make the auras affect warframes, not enemies.
