Champion Idea (input needed)

So I'm not some pro or nothing but I kinda had an idea for a champion in league, the idea is kinda like a swarm or swarm mother type champion. If any of you guys have any feedback suggestions tips or comments please help me create and improve. First off, I envisioned this champ as a mana-less mage or tank in the jungle, using its E as a gank tool and with an ultimate perfect for team fights.

P- Growing Swarm- So the passive is pretty generic shield, after using abilities the size of her swarm increases and she grows in size, when the shield is fully charged she has minor damage reduction and her shield has a effect, damaging enemies that attack her. When at full stacks her other spells are empowered.

Q- Swarm Workers- Very much like 's Voidlings, this ability would be her bread and butter. they would have increased armor and damage based off of her passive, and would have a cap based on level so she wouldn't have infinite workers, these would also work with her other abilities. At full passive stacks the workers become Swarm Brutes, slower, tankier, and larger.

W- Stalking prey-( Insert name here) Becomes un-targetable for a moment then re-apears after a second at target enemies location. (not sure if this should do damage) At full stacks she can use this ability 3 times in a row as a dash.

E- FLYYY!!!!- Shoot an like skillshot, your workers or brutes run there, knocking up enemies in their way then you can reactivate to dash to her spawns. With full stacks her reactivation deals a second wave of damage.

R- Plague- Her swarm expands in an area like 's ult dealing damage over time to all enemies in the area, and slowing them while they are inside the area. Fully stacked, workers and brutes are given boosts and all abilities used in the area stun and silence enemies.

This champion is supposed to be a jungle mage centered on mobility and I'm really new to this kinda thing so please don't be negative and please give feedback![slayer-jinx-catface]
