"Without nade, healing would be too powerful"

[Hyphen-21921]

Yeah this sentence is absurd:
Anti-Heal is a useful mechanic for the overall health of the game as it helps to ensure that healing never gets too far out of control.

Anti-Heal should only be used or available as a Combo for an ultimate, like a complement. Nade should just work on allies and Nano should maybe give Anti-Heal to the attacks of the Nano’ed Target for 3 seconds.

Also:

"We cant change Bio-Nades % because of UI confusion"

Its almost as if 100% Anti heal should not exist … and it should be something like a “poisoned” effect, where you lose 20% of your HP on top and that can’t be healed for the duration: Ana’s duration would be 3 sec JQ duration would be 6 sec Done. Balanced. You can even lower Ana’s CD back to 10.
