Bad against:

Ana: Biotic grenade prevents any type of healing for Moira (including her basic attack self-healing) . this is a huge threat to Moira. especially if she cannot use Fade yet.
Anduin: Anduin can pull his allies back to himself to save them from biotic orbs.
Illidan: Evade makes it harder for Moira to restore her Biotic energy.

others:
heroes withstun,silence orpolymorph interrupt Coalescence as it is a channeling ability.
heroes withstasis can avoid Biotic bind effect.
heroes that can escape easily are a sabotage to Moira. without Biotic orb her only other source of healing relies on her basic attacks.

Good against:

Probius: Probius' low basic attack damage makes it harder for him to take on Moira alone if he cannot warp in a pylon during a 1v1 fight against her.
D.va: Moira can avoid Self-destruct by using fade. she can also save allies from it if she chose the Shadowy experiment talent.
Chen: if Chen stops to use Fortifying Brew, Moira can basic attack him to restore more Biotic energy easily.

Others:
Heroes with low mobility can die easily to Moira.
Heroes with abilities that have high cast delay are predictable enough for Moira to escape from it.

Works well with:

Mephisto: Biotic bind can multiply the damage of consume souls against binded enemy heroes.
Zarya: Gravition surge can help Moira kill enemies easily with Coalescence. also Shield ally can save Moira if she cannot use Fade yet.

Others:

heroes with great crowd control can make a good team with Moira.

Works bad with:

Deathwing: because of his trait, aspect of death he cannot be healed. so Moira's presence is irrelevant for him.
Mal'ganis: Mal'ganis can swap his health bar with enemies at anytime. so Moira's healing won't be that helpful for him.

Others:

heroes that don't rely on healing or cannot be healed at all won't make a good team with Moira.

Tips and gameplay:

playing as Moira:

Moira is a healer who has both great healing and well damage so she can handle 1v1 fights on her own since she also have self-healing.
ability strategy:
-Biotic energy (Trait):Despite not being a mana user, Moira still relies on Biotic energy. even in 1v1 fight if her self-healing isn't enough, she needs it for healing orb.
-Biotic grasp (Q): this is Moira's first healing ability. it has a really good healing but for allies and not Moira herself. this ability also costs Moira's Biotic energy. so make sure to use it wisely.
-Biotic orb (W): this is Moira's second healing ability and her first damage ability. it does good damage and excellent healing. you can choose the type of the next orb by activating your trait. remember the healing orb costs Biotic energy.
-Fade (E): using this ability will make Moira invulnerable and makes her escape but also makes her unable to do anything while teleporting.
-Coalescence (heroic R): this ability makes Moira to channel a large beam that heals her and allied heroes and damages enemies. but remember that this ability can be interrupted by disables.
-Biotic bind: this ability links 2 enemy heroes to each other. causing all harmful effects to apply on both targets.

Playing against Moira:

-despite being a healer, Moira is actually a good hero in 1v1 fights. burst damages and healing negators will be useful against her.
-Biotic grasp is a massive healing for Moira's allies but not herself. so make sure to get rid of Moira before attacking the enemy hero near her.
-Damaging orbs can be really harmful due to their unlimited range. healing orbs heal Moira too.
-Fade allows Moira to escape from fights easily. so make sure to not waste all of your powerful abilities on her before using fade.
