well since you can now drop engineering and get the other side, I wanna try and pin down a few things to see whats REALLY worth having long term...
after all, while there are alot of recepies that can only be made by one spec, alot of them are able to be used by both. this divides all recepies that are in a spec into one of two categories:
1. items that are only useable by the person of that spec (ie the item itself says "requires gnomish engineer" or the such). these can only be used by a person of that spec
2. items that are BoP, but not "requires xxx engineer". these items can only be created by one type of engineer, but if you drop engineering and pick it up again (yes, leveling to 300 twice) then you can use it as goblin engineering even if the item is otherwise gnomish engineering
3. items that can only be made by one type of engineering, but are neither BoP nor require one type of engineering. these items require no special effort to gain other than having an engineer of the other type make it and either sell it on AH or trade it to you.
since the information on the internet is either inconsistant or incomplete for most of this stuff, and I can't get a hold of most of the items, could engineers of the two specs please help me out and sort the specialized recepies into one of these three categories.
I would also like to know which items can break when used (and thus would require the help of a specialized engineer to use again). I know many goblin items work like this, but I dont know if any gnomish ones have this issue.
thanks for your help!
