Part of the problem with earth is that a lot of flights don’t want to battle them. Battles are fun when you might have a fighting chance, not so much with a curbstomp. People were confused enough when Arcane challenged Light. The only flight that might stand a chance, numbers-wise, would be fire, and realistically it would have to be with massive support from at least one other flight and a crack dom team stepping in.

Water might have a shot but I think they gave it a try and it was rough.
