Good Idea!
In fact a lot of server forbide the Mining Laser because of easy grieffing with, even if the serv have pluggin for protect certain zone.
So you can't mine with in Multiplayer, and I think a more advanced drill should be added.
I already think to something like that:
"Abrasive disk"
=diamond
=Tungsten Ingot / Advanced Alloy
= Nothing
Tunneling Machine
__
__
="Abrasive disk"
Rest is obvious.
It could have 3 modes:
Normal: has the same effect as diamond drill, but make you directly drop items mining (what could help you when mining laser on that f***ing lava), maybe at a speed a little bit higher. Consume 1.5* the energy consumed by the diamond drill per blocks mined.
Mining: Mine directly 2 blocks in the same time that the first mode. Cost 4 * more energy (so 6* energy cost for diamond drill, but it means 3* more energy PER blocks)
Useful for ... mining
Excavation: Mine 3*3=9 blocks in the time needed for mining one. This fact will cost 30 * the energy needed to mine 1 block with normal mode, so 45 * Diamond drill energy cost.
Very useful for people who want to dig big hole without using Terraformers.
