Where will the NAVI core end up?

At this point i doubt if anyone would stay. Maybe Ange1 only.
Zyppan - KOI or TL. I think for his sake it'll be better to be part of the new KOI super team as a flex player.
ardiis - BiliBili
Suygetsu - VIT or Fnatic. If Fnatic sign up Suy, it will be scary times for EMEA, unfortunately.
Shao - KC/TL/KOI/NAVI. Small chance he stays at NAVI, most likely will be poached by TL or KOI but won't be surprised if KC throw a bag at him too.
Ange1 - doubt any team would bid for him so i can see him stay as IGL or HC at NAVI.

doombros - VIT/KOI

Boom esports aka BME is an esport organization mainly made for Boomers, they've went international several times and known for their godlike aimers alongside their insane chemistry proved by the infamous 'Rope incident' against OPTIC.

ardiis needs to save tl with his sage plays

Suygetsu to fnatic is not happening, boaster got offended by Suygetsu waiving at him once

I think NAVI should keep ardiis, suy, nd either shao or zyppan. I would rebuild around those 2 first though.

'zyppan' and 'superteam' in the same sentence referring to 2025

I think you’re forgetting GiantX as a likely destination

And also KOI already has a coach
