yeah thats true, zarya is easy to punish when there is coordination
but on less coordinated enviroments, she run rampants due to the lack of fire-moderation and spam damage, making her charging up easy
as well as the fact that they heavily reduced her skill ceeling with the changes they had been giving her.
honestly ,for zarya id do this:
it should leave her in a nice spot, reducing her power in the lower ranks while increasing it in the higher ranks where people know how to retain charge
