Champion Concept - Brood Mother

An idea for a new melee void champion. Visually she'd be similar to a hydralisk from StarCraft with a long snake like body and preying mantis style pincer arms. I don't know nearly enough about numbers in the game to come up with balanced stats for her or her abilities, but conceptually I like the idea from a thematic and gameplay standpoint. I'm guessing she'd probably fit in best in the jungle but she'd potentially make a decent solo laner as well.

Passive - Vile Brood Begins the game with two stacks of her passive. The brood mother gains a stack of her passive for every champion takedown, every large monster, and every X minions or small monsters. Whenever the brood mother casts an ability, she summons a broodling for every passive stack and then resets the passive stacks to zero. Broodlings function as pets that follow with the brood mother, don't time out, and get progressively stronger based on the brood mother's stats (i.e. they get greater attack speed as brood mother builds attack speed, same with health, movement speed, attack damage, etc.) Brood mother heals based on a % of damage dealt by broodlings.

Q - Unwilling Host Mid-range skill shot. Any enemy champion, minion, or monster hit by the skill shot takes damage, is slowed, and is marked. An egg sac is stays attached to the hit target and after a short delay, the egg hatches and X broodlings appear on and attack the marked enemy or monster. Immediately after hatching the hatched broodlings briefly have bonus movement and attack speed.

W - Feeding Frenzy Passive: Broodlings gain life steal based on brood mother's level and a % of brood mother's lifesteal. Active: Brood mother's next basic attack is empower. If she kills the target of her next basic attack, she will consume them replenish a portion of her missing health and immediately gaining X stacks of her passive.

E - Ensnare Brood mother and her broodlings dash toward a target enemy champion, minion, or monster. They take some amount of magic damage and are stunned for X period of time. All broodlings gain a brief burst of damage.

R - Void Swarm Passive: Brood mother generates an additional stack of her passive every X minutes/seconds (whatever would be balanced) based on level. Active: Brood mother and her broodlings again a burst of speed, and all broodlings alive immediately after the ult's casting gain a stat boost to damage, health, armor, and magic resist for some reasonable duration.

Strengths: Good dive potential with ensnare, as well as decent CC from her Q slow and E stun. Good sustain through her W and the lifesteal from her broodlings, and good chase potential from her slow, dash, and ultimate speed boost. Not destroyed by single target CC as her broodlings won't automatically be subjected to the same CC as the brood mother.

Cons: No AoE abilities so she's very single target focused. Pretty reliant on her broodlings so fairly susceptible to AoE damage from others. Melee champion without a lot of harass from a distance, so struggles when they can't easily engage on someone/pretty reliant on the E to get on top of someone initially. Would be susceptible to being burst down as her great sustain would be balanced out by relatively low base stats and health.

I would envision that the ideal build would be attack speed + lifesteal to capitalize on the fact that broodlings can lifesteal up and they heal the Brood Mother based on their damage dealt.
