I think it was at its best once Jeb started to take the reins. Notch wasn't really good at adding features that were actually fun to play with. I liked that they were willing to take risks but that quickly soured as it pairs extremely poorly with their excessive traditionalism. It took like 5 years for them to undo the disastrous combat changes when it became quickly apparent that they sucked, and the hunger/sprinting mechanics are still a pure cancer to the experience to this day. I want to see them make big sweeping changes like in the earlier days while also not being afraid to dial it back or try again if it ends up not being fun.
