Style choice. When you're making the planks with the blood, and not later on with the Sawmill, you're making the things you did in life. We all know that life is tedious. You're in denial. You still think you're in life.having to make enough planks or cobble to jump a 70 block gap, and having to make said logs one at a time is unnecessarily tedious. That mixed with the tired emo alternative rock band references makes this not a pack for me. if only i had a hopper to start with i could dump my chopped wood in the alter in bulk instead of one at a time... that's not a challenge is busy work.
Anyway, it's this type of grinding, or I can have you right click on a sieve all day. This is a much more interesting and risky way of doing it.
No comment on the music part though. Everyone can like their own genres.
