mining has completely lost the fun, diamond generation is VERY high, every place i go has tons of diamonds, i got 2 packs of diamonds very easily in just 1 hour mining, before 1.17 i wouldn't even get 20 diamonds in that time.
"Captura de Tela (127)" shows how much diamonds I got 26 minutes mining, "Captura de Tela (129)" is the proof.
it was 26 minutes with the difficulty on Hard, I had breaks to kill mobs and cook, it was approximately 20 minutes exploring the cave, this shows that the amount of diamonds is exaggerated
Conclusion: I got a Diamond Full Set in less than 1 hour playing, what's the fun in that?
Edit: To be more exact, it only took me 18 minutes to get more than 1 pack of diamonds, Screenshot(131) shows the moment I got my first 2 diamonds to the moment I stopped mining
