Wonder if adding a few more options in the Game Options -> Block Durability might be a win?
Right now it offers 25, 50, 100 & 200% (I think). Add in 125, 150, 175. Heck maybe even 225, 250.
This is coming from dev comments on what the Difficulty changes, which I think was just Damage Player does & Damage Z's do to Players.
Point would be, maybe, that those that like to build early on would have a pretty focused option to make that a bit more doable, and could notch it back to keep the pressure on.
Just a thought
Edit: damn it. I wouldn't want this to effect boulders, dirt, etc., and I have no idea if it does or not...
