Highly necessary
If I wrote, "X is necessary for Y," it would mean, "If there is no X, then there is no Y." (requirement)
If it is not a requirement, how do you write it?

"X is a factor that contributes to the establishment of Y."
X is an important element for Y."
"X is a cause of Y."
None of this feels right.nishio.icon
How about, "X's contribution is high."
Considering that you initially wrote "need high," maybe the nuance you're trying to express is packed in "degree high."
