The Overmind

The Eternal Will of the Swarm

The Overmind is an unconventional global Support who does not enter the battlefield as a traditional Hero.

Instead, the Overmind replaces its team's Core and transforms the allied base and Minion waves into a living Zerg colony.

Allied Minions become Zerg organisms, defensive Structures mutate into Zerg equivalents, and the entire Swarm slowly regenerates Health over time.

Unable to move or fight directly, the Overmind commands the battlefield through evolution, Creep, specialized Zerg strains, and global control of the Swarm.

Rather than controlling a single Hero, the Overmind controls an entire living army.

Combat Trait

1
The Swarm

The Overmind replaces the allied Core.

Allied Minions and Structures become part of the Zerg Swarm.

Melee Minions become Zerglings.
Ranged Minions become Hydralisks.
Wizard Minions become Queens.
Catapult Minions become Guardians.

Towers become Sunken Colonies.
Forts become Hatcheries.
Keeps become Hives.
Healing Fountains become Zerg Colonies.

Zerg Minions and Structures regenerate Health after avoiding damage.

The Overmind and his Overlord project Psionic Influence.

Abathur is the "working" version of Overmind, but even if we ignore that, this concept is simply impossible to balance:
1)I do not think a character should be able to "reskin" the map. This creates a LOT of confusion and visual clutter. It feels like something for the Brawl mode.
2)Making all Structures heal themselves is an extremely flawed idea. You are forcing the enemy team to siege as much as possible.
3)[Overlord] being able to travel over terrain (I assume this is what "flying" means) requires him to be easy to kill, but since you have no "influence" on the map without him, he has to be tanky, which leads to extremes in both cases.
4)[Ensnare] reducing the Attack Speed of Minions makes sense, but Heroes? It is difficult to tell how good this is without knowing the range/radius values, but this still makes it much stronger against certain characters than it should be.
5)[Plague] reducing the healing received baseline is not the best idea. Again, difficult to evaluate, but it can easily make early game fights unfair.
6)[Rally the Swarm] is very clunky. There does not seem to be a way to manually select the units you want to rally, which leads to problems. Also, why does a Hydralisk cost more than a Zergling? Melee Minions are more valuable than Ranged Minions due to how much more damage they can take. In addition to that, making the rallied Zerg scale with the Overmind means that [Rally the Swarm] changes their stats upon being selected, causing a lot of confusion, maybe even making them weaker than the default versions, excluding the rally bonuses.
7)[Dark Swarm] reduces the damage of ranged Basic Attacks... but what is a ranged Basic Attack? How does it work against Zarya, for example?
8)[Dark Swarm] reduces the enemy vision by how much exactly? This defines whether it is strong or overpowered.
9)[The Swarm Hungers], while conceptually fine, is just... boring? It just gives you 2 empowered uses of [Rally the Swarm].
10)Since this kit completely revolves around [Overlord] being alive, why give it to the Overmind in the first place?

Talents create even more problems:
1)[Metabolic Boost] breaks the "flow" of your Minion waves. You are practically helping the enemy team by making the Melee Minions arrive sooner than the rest.
2)[Cellular Regeneration] is impossible to evaluate.
3)[Pneumatized Carapace] is very dangerous.
4)[Ventral Sacs] makes [The Swarm Hungers] less powerful.
5)[Overseer] is extremely toxic.
6)[Virulent Plague] makes [Plague] deal more damage to Minions and Mercenaries... while it already deals increased damage against them?
7)[Muscular Augments] breaks the "flow" even more than [Metabolic Boost].
8)[Metasynaptic Node] encourages button mashing over properly using your abilities.
9)[The Swarm Endures] is fundamentally broken. It is basically telling the enemy team that they will not win this one.
10)[Cerebrate Network] is interesting, but... how do you control [Overlord] in the first place? I thought it was like any other Hero, but this talent makes it sound like it is the clunky commands of Rexxar's Misha and Raynor's Banshee.
