/ah is back. It's more beneficial now to use manual farms because McMMO skills were added, these make it a lot easier to earn more of the item you're farming. It also adds more playing quality because you're actively doing things instead of relying on automated machines. If you think about it, McMMO adds a new way of playing Skyblock and also makes it more fun to play for unranked/default players.
Skyblock has always been a little bit easy to play, whereas with the new updates they add an edge to it where you are struggling more for items, but at the same time are rewarded for the struggle. If you grind hard enough you'll earn more than you could with an automatic farm.
