While i see these changes going in a good direction, they dont seem quite there:
Passive:seems acceptable for something you get for just being there.
Mind Control: the damage enemies deal to each other gets to irrelevant numbers as the level go up, what you need in order for the ability to be useful is make it so you have an extra gun, so it can dps and kill enemies, if the numbers on the multiplier are high and consistent enough then fine, if not i suggest making it so across those 4 seconds it charges dps from your damage, instead of a multiplier or flat damage, making it so the target either attacks faster or gets the appropriate multiplier to their stats. You could also consider letting melee and/or allies contribute to the charge. Either way the goal is to make it so the target can kill other enemies at least as efficiently as someone with a properly modded weapon.
Psychic bolts: great, plain great. Will have to test for usefulness and numbers.
Absorb: to begin it will be nice to have a counter on how much damage we will end up dealing. Increase it´s range please. It has the same problem as her current 1 does, you are dealing the damage the enemies output, it kills frames relatively easy, but barely chips other enemies health bars as the levels rise, even when multiple enemies are charging it. So to fix that problem, make it similar to octavia´s 1, enemies want to shoot it really bad and the damage back has a multiplier, to balance and avoid spam and/or set it and forget it, you can increase the the drain (make it cost its worth) 10 or 15 unmodded with an unmodable max of 20 or 25, you could also give it a soft cooldown, what i mean by this is make it so the drain will remain a short period of time, 8 seconds or so, in which you would use the rest of your abilities to survive, and help the squad, you could also make it so the ¨current drain¨ decreases over those 8 seconds, you so can more easily use it in a pinch.
spellbind: please add more range, 10-15 meters would be amazing, and add some duration 20 seconds seems more reasonable.
tribute: the biggest problem i see with this is that you need an enemy to cast it, but most of the time everything is dead, so why not allow us to cast it from corpses, 1 buff per corpse, and if the body exploded or was cut in half then you could get the buff from any part of the corpse.
-dust: change it to flat damage reduction on pick up, and if titania herself picks another one up, it refreshes for the whole squad on affinity range
-thorns: same problem with nyx 1, enemies dont deal enough damage to damage each other, you could change it to have a chance to reflect damage with a multiplier.
-entangle: just numbers, buff it a bit the max slow like to 35% or let it be affected by strength
-full moon: buff to like 200% or let it be affected by strength
it is also important that the current play-style and appeal of the warframe stays relatively the same for those who already like them, and give them alternative play-styles so more players give them a chance.
