Reposting this for clarity.
Each team deserves their spot in Iceland. They don't make it? They'll have to do better next Challengers. Do not belittle other teams' effort and journey just because your favourite team didn't make it. If you think Gambit or any team should make it instead of KRU or any other minor teams, Then it's just the regional differences. Gambit failed to beat Fnatic? Then be it. That's the EMEA for you. You probably know how close the region is relative. KRU fought tooth and nail by beating Infinity? Then that's LATAM. A whole set of challenges and differences that each team needs to overcome.
And it's still not a reason to put down each team and change them with another just because the said team lost to the ones that eventually qualified. There are the winners and the losers. There are the ones that qualified, and the ones that are watching from their home/team setups. That's how it is.
