Engineering has always be rather lacklustre. Only granted the player to build machines (which can be found in community halls anyway) and to produce tools, IF the player has Tinker 4 or 5, (which can be brought very easily and at a cheap price anyway from the NPC tool stores) so, I propose this, firstly, be able to produce upgraded tools which can't be brought from NPCs ( I do realize this has been covered in many many forum posts already) but, also, have perhaps a small, passive buff, when creating powders/smelting/tinkering and other 'science' based activities. Perhaps, something like a 5% reduction in energy used.
