how did we let this happen
No, it's not though. I'm not even necessary arguing how good these teams are. I'm just pointing out how EMEA legit needed DRG to qualify to playoffs. Maybe you could make the argument T1 is just as bad, and thus G2 is on the same level, but it's just DRG was the worst rated team coming into the tournament.
Answer the question though, if LEV really is a 3 player team, how did they finish 3rd in the Americas? And what does that say about the level of play in the Americas league?
In reality LEV is a legit team of course, and you're just depreciating them (and the Americas as a whole) for the sole purpose of being toxic to EMEA.
