The average block time is ~9.8 minutes, which means that we may need a longer time to return to normal fees.
Perhaps I misunderstood your comment but I wouldn't say that the average block time directly impacts the fees that are being broadcasted. Perhaps you were saying that there should be more discussing in increasing the mining time? I don't see how that would impact the fees in any meaningful way.
The difficulty will be adjusted in ~3 days, which always tries to be an average of 10 minutes. If the average is less than 10 minutes, this means that the difficulty will increase to maintain 10 minutes, and since the difficulty will increase, a longer time to find blocks and if the number of unconfirmed transactions continues to increase, it means that we will not see lower fees soon.
