hi as the person who seeded this event
this is actually not far off from the number i predicted for DQs based on other events entered!
For an event this size approx 30-40% DQ is really not that crazy overall for R2, but anyone who didn't show up to play in a turbo loser :)
I'm human so there might be a few errors in my counting, but here is a quick breakdown.
320/1,022 (roughly 31%) of entrants for Rivals of Aether II were flat out DQs. However, even removing those DQs, it just swaps places with Strive, the next game down, in terms of entrants.
