I had thought about that, and it would indeed be quite a lot of fun. That's one reason I won't be disabling frames and frame equipment. I do, however, think they should be special and rare, not knocked together on a whim and thrown into battle. It should hurt when your airship is destroyed, not feel like "Eh I'll just wait till my frame quarry digs out another 12 chunks and make two more airships whatever"
This was a few pages back, but caught my eye.
When my airship gets destroyed it does hurt, and it would still hurt if i made it for free.
why? because i invested a lot of time building it.
The true cost of anything in minecraft should be calculated as Cost=Buildtime+Miningtime+Craftingtime.
so even if we take out the miningtime from the equation, frameships is a huge investment.
And that why you should not restrict frameships, but rather restrict the block breaker.
It's the most simple way to control frame quarries, and it only requires you to restrict one block.
If the block breaker is just expensive enough, UU generation is removed, and teleport tethers are restricted, it would make frame quarries much more limited, even to the point that it could be balanced.
Our ridiculously large frame quarry(it has 2 rows of block breakers from the surface to bedrock!) does not really mine that much ore, let alone diamonds. The thing that makes it OP is that it digs so much cobble, that can be turned to UU that can be turned into anything.
Without UU our miner would be much weaker. And it would have slightly less than 250 block breakers if the were restricted(or just required diamond pickaxe.... why does it only need an iron one? Eloraam!!!!)
