Had to fight it on the console version when they added more achievements, and it was definitely frustrating (especially when I tried digging underground to escape and died, so I had to run back into the nether naked and try and grab my stuff
) but not quite "hard" to me. Sounds like the new dragon is both more difficult and certainly has ore of an endgame around it so that's nice. I assume someone's already working on some sort of farm for the dragon to get the breath.
EDIT:
Good news everyone! The new rain sounds are pleasant and gentle, instead of infuriating and oppressive! Huzzah!
EDIT2:
Also, can someone explain how to dual-wield? Zero and I were stumped :|
