Is it confirmed that GEO is nerfed -75% in Odyssey?

If so, why? That is too much to the point where it makes it useless. Why not -25%? At least let me still use my Idris GEO in there. I find it crazy that I put all the work, time and effort into finishing it just to not use it in this end game content.

I'm not asking to make it over powered and just steam roll through content, but having a REMA should give an advantage for the work put into it, no? To basically make the job useless in there, you might as well say don't play it in there, and that's not cool.
