Exactly the point... mining's not broken. Still plenty of stuff can be done with it.
A lot of "Mining is broken" is actually just "I can't get LTDs or Tritium", which is a whole other issue. Problem being, fixing that will just make mining OP again. Building mechanics on top of other unbalanced mechanics always leads to this.
But it is broken. And that can be seen from the Issue Tracker. Everyone knows mining was too good. Whether you were against mining or an avid miner. Of course it was too good. So a nerf was inevitable. But the nerf broke some things. It's hard to see where it is currently without those smaller issues being fixed. If fixing those issues makes mining OP again, then another nerf will probably follow. That doesn't mean the problem doesn't need to be addressed. A bugged feature to what was an overpowered problem doesn't make it right. We'll see what FDev does. Though from my short time here, it seems when something is fixed, another thing gets broken. Scary cycle.
