Okay, I'm just a little upset right now.
Situation was like this:
I've been re-building my house, aka re-arranging the walls. While mining the old walls off, I accidently hit my MFSU, which broke. But, i've just klicked it once by accident. I mean, I didn't mean to break it. (Been on a smp server, so stop get tmi and cheat it back, lol.) After testing in SSP, I can confirm that breaking it takes roughly half a second.
My actual point is, what do you have to build a case out of reinforced iron, advanced alloy and even carbon plates when you get something you can break twice as fast as a cobblestone? I mean, for physics sake, a MFSU (and all other (at least) advanced machines) should be mineable as fast as the machines in IC1 with a drill (which means to be way slower). I mean, I didn't need to fear to break machines in IC1 by accident, since it took like 5 seconds to mine them (with a ddrill)... but now.... yah, there goes my MFSU, and I won't get it back "'cause its my own fault".
