This has been suggested a few times before, but none of the posts have gained much traction, so I'll summarize what they said here. The crops and generators take too long to respawn. It's fine up until around the second nether biome and savanna biome, but at those two points the game goes very fast from 'fun' to 'I guess I'll just pop on every other day because that's how long these things take to regrow, and then log off for another 2 days'. I agree that Skyblock is meant to be grindy, but this isn't grindy, it's waiting doing other stuff for 2 days and then logging back on just to chop trees and log off again. I would like to see this changed, where stuff takes no longer than 12 hours to grow, at the maximum, to make the game actually engaging for players who want to play it.
