Guild Wars 2

Hi,

is it possible to upgrade Ghostly, Mighty and Versatile Mighty Infusions to +7 agony resistance?

I mean, they are so expensive, but useless in T4 fractals, which kind of defeats their purpose.

They are not useless you just need to spend more on Agony infusion to get the 150 cap.
