So their are still some dumb dumbs who don't understand why the seeding was created like that so let me briefly explain :
Riot made this seedings in a way in which all the regions are considered to be at the same level, so they didn't take into consideration that EU and NA are at a higher level (AS OF THE RESULTS IN ICELAND DONT ATTACK ME BRAZIL FANS)
So for Group A since Acend got 3rd and SMB got 2nd they got placed with KR's 1st seed. On paper it would look like a easy group for VS since they got first seed but if you take into account the skill level of ACE and SMB it is the hardest group in the bracket.
Group B has NA's 3rd seed and the 1st seeds of Japan, LATAM, and Brazil. This group contains all the first seeds and one third seed so technically it should be difficult for envy but since NA is basically one of the favorites its considered the easiest group.
Group C and Group D make sense so I'm not going to explain.
In my opinion it would of made the groups much better if one of either SMB or Acend got moved into Envy's group to even out all the groups but too late now!
