Most underrated teams ever?

Be it before franchising, name the teams you think were/are highly underrated and had huge potential but couldn't really live upto it.

The Guild lineup of old with Sayf, Leo, Koldamenta, Trexx and Yachine was INSANE. Just couldn't really pull it off though.

Xset lineup with Cryo, Dephh, zekken, bcj and Ayrin was stacked AF too but couldn't pull through again :(

TL with Jamppii, Soulcas, Nivera, L1nk/Dimasick and ScreaM was another insane lineup which couldn't live upto their potential due to their habit of choking and their lack of IGLs. Really felt heartbroken when they lost to Acend and Optic respectively in champs ):

NaVi of old with Cloud, 7ssk7, SmartSeven, Jady, Dinkzj, Duno all with the shuffles was also a very good team that just underperformed IMO.

TL had no IGL, end of story for that team.
Xset was really good at the end of the year, beating EMEA powerhouses like FPX and FNATIC.
Guild was also insane, just didn't work out.

Eg until the lower half of vct americas and even before coming at this event

russ was better than yacine, yacine move made it worse
