Moirai - Warframe of the Fates (?) Concept (Feedback welcome)

[kushemon]

Passive - Scaling with the amount of buffs active on Moirai at a time, increase the evasion of Moirai and her teammates (within affinity range).

1st Ability - Two Faces:
Moirai flips a coin, indicated by a small icon above her ability bar.
If the coin lands on heads (*different name for coin sides pending), Moirai will recover her shields.
The percentage amount of shields recovered scales with Ability Strength.
If the coin lands on tails (*), Moirai will lose all of her shields, triggering a Shieldgate, even if her shields were not full.
The Shieldgate resulting from a tails flip will not scale upwards with shield amount beyond the initial max.
Scaling with % of shields sacrificed, Moirai grants a damage buff to her and her teammates (within affinity range), until her shields are fully recovered.
If the coin lands on tails twice in a row, no Shieldgate will be granted, any current shields will be lost and Energy will not be refunded, but the Buff Duration and Strength (again, scaling with shields sacrificed) will increase.
The energy cost of this ability is not affected by Efficiency.
(The buffs from 1st and 3rd ability stack.)

2nd Ability - Machina Sutura:
Hold to select targets. Fire a barrage of needles at the selected enemy.
The enemy is knocked back (distance scaling with Ability Range).
If they hit a wall after being knocked back, they will be pinned, disarmed and unable to move for a few of seconds (Amount of time stuck increases with Ability Strength, not Duration).
If the enemy fails to hit a wall/object after being knocked back, only a small amount of Slash procs will be applied.
This ability does not deal any damage if an enemy is pinned.
This ability is capable of crowd controlling any enemy, even if they are affected by overguard. Normally un-crowd-controllable bosses can be affected too, with exceptions.
While holding down the ability, multiple enemies can be selected, however for each enemy selected, energy will be spent.

3rd Ability - Borrowed Barrage:
Moirai emits a wave in front of her. Any enemy, wielding a gun with a magazine function, caught within this radius will be forced into a reload animation.
If Moirai is holding a primary/secondary weapon, the magazine will be instantly replenished.
Depending on how many gun wielding enemies were hit, Moirai increases her and her teammates weapon damage until reloading. Boost amount scales inversely with ammo amount.
Scales with Ability Strength, Range and Duration.
(The buffs from 3rd and 1st ability stack.)

4th Ability - Intertwined Fates:
Intertwine/sew together the souls of all Warframes present. Moirai emits an expanding wave in their affinity range.
The current health of all Warframes caught within that area will be added (e.g. if there are three other warframes, and every player in the squad has 2000 health, the result would be 8000 health.)
This amount is then added onto all the warframes touched by the wave, minus their own health, indicated by a bar of different color.
Whenever a teammate receives damage to health, the amount of damage received will be removed from all other warframes as well. 
The damage transference will not affect other player's shields and health bars, besides the one created by Moirai. 
Shields take priority over the health of Intertwined Fates. 
During a shieldgate window, this health is not affected.
"Borrowed health" amount can be increased with power strength (e.g. 200% PS = 2x of borrowed health).
