Chocohead : Thank's, I didn't noticed ^^'
Speiger : The enchantment system IS more than extremely broken, so far I only managed to enchant electric armor with anvils, nothing else works 
Well, if it's a feature, I won't complain 
Coolant is also an idea, but wait, cables in IC2 doesn't tick ?
I did and do IC2 crops, but I wanted to say is to add a way to disable the 5 copper/tin dust with 4 opposite dust ( copper/tin ) makes 1 small iron dust, so people that doesn't know how to use MineTweaker can do this ( even though it's very easy to learn, and for now I am using MT to disable this recipe ).
EDIT : Minor bug found : Cable fry in easy mode.
