BANE OF THE STRICKEN
-Each attack you make against an enemy increases the damage it takes from your attacks by 0.80+x%.
-Gain 25% increased damage against bosses and Rift Guardians. (Requires Rank 25)
-After applying 20 stacks you gain a 1+x% damage buff and 15% movement speed while active. (Requires Rank 50)"

this makes no sense the only time your stacking sticken is elites and rgs when you dont need additional speed. It also doesnt really fit with the theme of the gem (killing high hp targets)

BANE OF THE TRAPPED
-Increase damage against enemies under the effects of control-impairing effects by 15.00+x%.
-Gain an aura that reduces the movement speed of enemies within 15 yards by 30%. (Requires Rank 25)
-Reduces the amount of damage enemies affected by the aura do to you by 10+x%. (Requires Rank 50)

This is already a op gem giving it dr would only make it even worse. If the lvl 50 perk was going to be defensive it would make more sense to reduce attack speed of enemies to keep with the slowing theme.

NVIGORATING GEMSTONE
-While under any control-impairing effects, reduce all damage taken by 30.0+x%.
-Heal for 20% of maximum life when hit by a control-impairing effect. (Requires Rank 25)
-Your Defensive skills now hold 2 times the amount of charges.(Requires Rank 50)

This gem is to broken to tweak, it needs an overhaul. Theres plenty of classes that can block cc so it does nothing. Also not all classes have charges on defensive skills.

It should be more like

-When targeted by a cc spell (even if your immune) gain 10+x% increased damage and take 30+x% reduced damage for 30 seconds

- You become immune to all cc effects

-Gain an absorb sheild for 100% of your hp when target by a cc spell

MORATORIUM
-25% of all damage taken is instead staggered and dealt to you over 3.00+x seconds.
-10% chance on kill to clear all staggered damage. (Requires Rank 25)
-While suffering from staggered damage your blood spills outwards in
all directions, dealing 1000+x% of the amount of damage you are taking.
(Requires Rank 50)

Again needs to be altered

- 25+x% of damage is staggered over 15 seconds

-1% chance on crit to clear all staggered damage

-Clearing staggered damage causes your blood spill thing or alternativly transfers the staggered damage to all enemies in 10-15 yards

MUTILATION GUARD
-Gain 10.0+x% melee damage reduction.
-While below 30% Life, you may move unhindered through enemies. (Requires Rank 25)
-Gain 500+x% Thorns damage and gain a 10% chance to ignore incoming melee attacks.(Requires Rank 50)

Thorns is getting its own gem. Sader builds with the new thorns set are already quite strong so not a great choice
