toughest groups in vct history

I'm not too familiar with the first year and half of vct, what are the toughest groups through the years and why?

Is this group B the toughest?

In champs, B

Champs 21 group D all teams lucky JohnOlsen was 1v9ing

Copenhagen Group A:
Optic Loud Guild Kru

Lock In, oh wait, it was an invitational mickey mouse

How do you define the Toughest Group, you mean teams in the group are highly competitive or teams in the group are having very tied games?
For the previous one, it should be group B in Champions İstanbul, and for the latter one, it should be group D in Champions LA.
Ofc the group B in seoul isn't tough at all😂GENG is dominating while FPX and TH are chokers, Sentinels is literally trolling.

relative to the region it's prolly group B at kickoff (from what i remember). in an international id say it's the group with loud and optic at copenhagen

Champs 21 group B had a strong Sentinels that had won 2 masters prior to the event with that roster, A very strong Liquid team that probably wins the whole thing if they don't play like shit against acend, but got 3rd. And the biggest dark horse ever imo KRU that beat sentinels to make it to play offs and got 4th.

Group B is always tough for some reason

group D imo of champs 2023, navi had a VERY close game against loud and could’ve won vs DRX

i know navi is a meme now but i lowkey became sad when they got eliminated by loud cause they were so close
