Swiss vs GSL format

In actuality it doesn't change much.
Just like in GSL, 2 wins and you qualify , 2 losses and you are out.

The changes for (8 team, 4 region) swiss would likely be:

1. Potential for no repeated matchups (normally swiss stages prevent repeated matchups, however riot has allowed repeated matchups in the past)
2. Potential for inter-region matchups.

Example of repeated matchup in GSL:
(BLG vs NRG) or (T1 vs FUT) or (EDG vs GIANTS) at Champions 2023 , swiss should reduce the repeated match count.

Most "issues" with formats stem from seedings and draws, this will likely be the same for swiss.

I mean, those 2 changes are pretty good though, no?
