Valkan’Arak the Insect Lord (A Huge Hybrid Tank Hero)

This is a hero based on one I designed for my friend's Warcraft III Moba that never saw the light of day. He was based on the Crypt Lord's model (Nyx Assassin). This suggestion will have Warcraft III placeholder icons and models. Numbers can be changed. I would just like feedback on the concept.

Dota 2 Model: A large and thick hero model that is modeled after a Goliath Beetle. His arms are like a Mantis Shrimp, built like clubs to beat opponents down. He has an insectoid face, with a mouth like the old broodmother model, unlike the other bug based heroes, he has two eyes. He has spikes on his back when he learns bladed shell.

Lore:
No one truly knows where the Insect Lord came from. Some believe he was a spiderling that was mutated by magic; others claim he was formed from a hive itself. All that can truly be said about Valkan'Arak and his swarm is that they will consume anything that is alive or was alive at some point. To him and all his children, war is just a means to feed on the dead without a struggle. To eat and to kill was the sole truth to the Insect Lord, and in this world, the only options are to dominate or be killed. They chose to be the predators and not the prey.

Abilities:
Bee Wave
Shoots a swarm of bees in a line (200 width, 800 range, travels at 800 speed). The bees sting all units by the wave, paralyzing them, and dealing damage at the end of the stun. Damage Type: Magic.

Level 2 - 1.6 stun, deals 115 damage.
Level 3 - 2.0 stun, deals 155 damage.

Mana Cost: 130
CD: 12
Flavor Text: Valkan'Arak's bees are a strong force that sabotages anything they run into with a deadly poison.
Notes: This is a straightforward stun ability. Allows ganking and initiating.

Returns damage dealt by physical attacks from foes. Also adds armor. Damage Type: Physical
Returned Damage: 8/12/16/20 + 8/16/24/32% of incoming damage
Bonus Armor: 1/3/5/7
Flavor Text: Against many foes, the Insect Lord's hide is a deadlier weapon than his claws.

Notes: A powerful defensive skill that counters dps carries.

Urna Swarm
When Valkan'Arak kills a unit, a Carrion Beetle will spawn from its corpse (works with denies). When Beetles die, they heal the Insect Lord. When this skill is activated, it kills all your beetles instantly.

CD: 10
Flavor Text: None can escape the eyes of Valkan'Arak, and the loyalty of his scouts is invigorating.

Notes: A reworked version of Nyx Assassin's old skill. This skill gives tanking power, pushing power, and map control.

Leech Field (Ultimate)
Passively drains the health of all foes in a AOE around Valkan'Arak by a percentage of max hp per second. Can be activated to put Leech Field into Overdrive, doubling the percentage.

CD: 110
Flavor Text: Everything the Insect Lord and his scourge cross dies. There are no exceptions, It's been said that he eats you just by being present.
Agh Scepter Upgrade: Increases AOE to 1000. Changes damage type to Pure, permeating magic immunity (stacks with Octarine Core).
Notes: This skill is actually based on the Boss of the 2nd Blazblue Game, Hazama's ability. I find it makes him a scary AOE carry and tank.

Voice Sample (Clancy Brown) (The Bald Guy's voice)


Relative Power Level: A giant monster with magical powers: Tiny, Tidehunter.

I updated his numbers. Also, if there is any input, that would be nice. :)

To me the Bladed Shield seems a little overpowered. To me damage return, an attack slow, and bonus armor sounds a little to much. Everything else looks great. He looks like he would be a really fun hero to play.

I've updated the hero, adapting to the removal of HP removal damage type for 6.82. Also, removed the attack slow portion of Bladed Shell to weaken his 1v1 potential. Any thoughts would be appreciated.

I'm updating all my heroes with the 6.84 patch changing everything, starting with this one. New additions include tabs on his cruel personality, his limited interactions with other heroes, and a sample of what his voice might sound like.

And in terms of gameplay, he's gotten his ult redone again, since everyone I talk to seems annoyed by it. Its now pretty much Necro's heartstopper with a life drain attached to it, and an active like Empowering Haste, to double the effects. And Aghs makes it into damage, so RIP blink heroes, especially since his Aghs would stack with Octarine Core.

Beetles were also nerfed, having 410 ms spiderlings that can burrow was a bit OP, so their ability to swarm a hero in lane was nerfed, as if they attack, they get 290 ms instead of 410.
