There's a few problems here, mostly revolving around Nyx's 4 and Titania's 2.
Mainly, enemy damage is several orders of magnitude below enemy EHP. A mid-high level Heavy Gunner will kill most frames in seconds, but takes hundreds or even thousands of it's own bullets to die. This clearly illustrates the problem with Absorb: Nyx is bleeding out her own energy and ability to act or play the game to return said damage back to enemies. Returning said damage is frankly useless, as returning 5 or 20 or 50 Gorgon shots does not matter when it takes hundreds to down the enemy and Nyx wasted her own energy pool to do this. Absorb needs a actual rework because of that even if we ignore the "Nyx decides to stop playing the space ninja game with cool movement to sit in her bubble, completely immobile".
This brings me to Tribute. Tribute is a very poor ability. It has 2 relevant buffs, and due to no scaling and poor numbers I can only barely count Entangle as 'relevant'. Going through them in order:
Dust: it's good. There's not much to say, it's a accuracy debuff with decent range you keep up forever. It's the only remotely redeeming feature of this ability.
Thorns: This is a waste of energy with no redeeming qualities thanks to how poorly made damage reflection is in Warframe. This ties in to Absorb: enemies have orders of magnitude higher EHP compared to their damage. And damage reflection in Warframe still deals all the damage to the Warframe, just then also reflects some back. This makes the buff completely useless, as the Heavy Gunner or Bombard or Tech hitting the squishy, MAYBE couple thousand EHP frame might take .1% of their EHP as damage back while Titania is smeared across the wall.
Entangle: This is the barely relevant one! A high uptime radial slow sounds nice. A impotent, low range, unmoddable slow does not. No points for guessing which camp this factors into, as it turns out a 25% slow with measly 10m range is not that good when most enemies have guns, the ability to fire them, and the ability to not be constantly hugging Titania to taste this aura.
Full Moon: This is a companion damage buff, in a game where most companions do crap damage, on a frame where the only good ability forces your companions into a pocket dimension where they cannot fight. It buffs Razorfly damage, but Razorfly damage is a joke and the Razorflies die within seconds of being summoned.
Both of these abilities have glaring root problems that have not been addressed. Buffing the numbers does not fix the problems, and does not even bandaid the problems due to how bad the abilities are to begin with.
