Make Fungal Growth not immobilize units but slow their movement. Units will move 50-70% slower. Numbers can be changed.
Make that Fungal Growth can't kill units but will damage them until 1 HP remains. It's like the Plague from Brood War but damage is the same as it is.
Reduce Fungal Growth radius of effect. It's really simple change. It's similar to Ghost EMP nerf.
Remove mana upgrade from Infestor Pit. It's similar to High Templar Khaydarin Amulet nerf.
Neural Parasite cant be used on Massive units. This change is mainly for Mothership steal balancing.
Make infestor 3 supply instead of 2. So you cant make too many of them in 200/200 unit composition.
Give Infested Terran eggs the same amount of HP as Infested Terran itself. So it's actually usefull to focus eggs before they spawn.
The fungal becomes a projectile. So you can dodge it.
Fungal Growth can affect your own units like Psyonic Storm/Hunter Seeker Missle or Plague from BW. So you will target enemy units more accurate.
