I don't know if this has been suggested (and I'm a bit to lazy to go through the 4 pages ;)). But this just came up when I deleted another "bomb diamond" compound.

Can't we just remove the "non-compoundable" items from the list where you choose the ingredients?
Because every newb seems to enjoy making a bombdiamond compound now and then.

Anyways, if it's been suggested, my bad, if not, then "can we fix it?" ;)
