Immorticia character concept(Idea)

Immorticia is possibly one of the character that a lof of people want to see in the game, and many people thought that it would be in gw 2 or bfn, but sadely she haven't, yet. And i Invented my own concept of how could this character, this concept really made me like the character and want him in the game, she could be the last prize of the october prize map, as it's the month of the lawn of doom event, which is the pvz version of halloween, and she's not just a witch, but also has commands a swarm of zombats.

  -Class: Support
  -Health: 100
  -Passive: her primal and 2nd ability have a vampire effect(heals immorticia by a small part of the damage caused to plants), she'll also transform into a ball of energy surrounded by zombats when sprinting, it moves slower than other characters while sprinting, but her hitbox is very reduced in this form, she'll also deal a bit of damage to plants nearby her while using it, which also has the vampire effect.
  -Primal-Zombat swarm: Launches a cloud of zombats, dealing damage in impact, and also to plants in the range of the cloud generated(note that this is similar to the primal attacks of alien sunflower, toxic citron and park ranger soldier from gw 1 and 2).
  -1st Ability-Vamperishing curse: Launches her zombats to the direction she's facing to temporarily curse plants with an area of effect, cursed plants deals less damage, have a reduced movement speed and are unable to use abilities, and zombies who damages cursed plants will get healed by a small part of the damage dealed, the curse will end immediatelly once immorticia is vanquished.
  -2nd Ability-Batsappear: Immorticia warps a further distance to the direction she's facing, cursing and damaging any plant she passes through.
  -3rd Ability-Witchery caldron: immorticia summons a caudron in front of her, the caudron will produce potions that can be collected by any zombie, providing a random and temporary buff(speed, damage or invencibility) or starting their health regeneration, and after a time the caudron will blow up, making a explosion that deals great damage to nearby plants, temporarily poisoning them, making they unable to use abilities or sprint, and take toxic damage over time, a similar effect to the one given by chomper's grody goop
  -Extra: While wizard can counter rose's abilities in many way, rose can do the same with immorticia's curse, rose's arcane enigma will automatically null the curse to rose herself, and boosting plants with it will also remove the curse from them, and using jynx on immorticia will remove the curse from every plant given by that same immmorticia, it also works when goatfying her, i know that in pvz 3 she got like that an organ mech, i think that it would be really cool to be implemented in her bfn moveset, but a mech probably won't fit for a support character, and i don't want her to be an attacker character as there are already way too many characters from this class in the game.
