Maybe you just underestimate this.
See, there are many player and the guilds are raiding MC. Its not like the old days. Everyone is more experienced and knows what to do and need for the next content.
And now, many people are farming herbs especially Black Lotus and store them in their banks. Waiting for the next content to sell them, step by step or use them for flasks to win the race.
Its a normal spawnrate.
What you dont really see is, that there are people who know every spot and have their timer for this respawn.
If you have time for this, you can see it when you random see a spawn of a lotus and then set your timer. Someone looted it. And when the timer expires, its often the same person again.
It sounds crazy, but with about 7k active player and up to 9k - its just overwhelming
