New Panda Barb Skills

Please please please PWI, make a new skill for barbs in panda form that allow us to take and hold aggro! I just want to be a tank! (Currenty, Barbs are switching to claws and Dex builds because they have no chance at holding aggro.) I made them balanced so both Stabbing Pain and Sacrifice would be interesting to manage your chi and play in order to hold aggro from any APS player. These skills are desperately needed by this class.

My dream panda barbs skills would be:

Skill #1- Like flesh ream, but creates the same hatred as a 5 APS sin with +5 R9 daggers would generate in 4 seconds.

STABBING PAIN
(must be in Panda form to use)
100 Mana
Channel 0.2
Cast 1.2
Cooldown 4 seconds
Costs 30 Chi to use
Deals base physical damage plus 4000 physical damage and greatly increases threat level. Note: increase in threat level equivalent to the threat level generated by a sparked 5aps sin with +5 R9 daggers)

Skill #2- An immobilize skill that lasts a decent amount of time, like 8 seconds. I don't need a stun, I just need something to stop players from kiting and mobs from running which makes grinding super annoying!

TORMENT
(must be in Panda form to use)
150 mana
Channel 0.2
Cast 1.2
Cooldown 20 seconds
Deals base physical damage +1500 physical damage. Immobilizes target for 8 seconds. Increases critical hit rate by 10% for 8 seconds. 100% accuracy.

Skill #3- This is the end all and be all of aggro skills. Pretty much guarantees you get aggro of everything nearby: but it will cost you. This skill allows a barb take and hold aggro from a sparked RRR9 sin with refined daggers (or better daggers that have yet to be released.)

SACRIFICE
(must be in Panda form to use)
Channel 0.2
Cast 1.2
Cooldown 4 seconds
Costs 2 Sparks.
Lose 50% of your current health and mana to create a 12M AOE dealing base physical damage +5000 physical damage and hugely increasing your threat level (threat level increased as follows: every 100hp and 100mp sacrificed generates the threat equivalent of one sparked sin attack with R9 daggers).
