Forum:Item Template - How to fill nx= and case=

As requested by DynastyW, here is my suggestion, not in a blog, since in the commentary section we would just mix up discussions and votes.

Introduction
Currently, DynastyW reworks the information about the availability of NX Rare Weapons from Supply Crates. His system consists about adding the MYST-N as superordinate for the Supply Crate MYST-N and its successors (Supply Crate MYST-Alpha and so on) in the variable |nx= while adding the crates itself in the line |case=. I asked him about his reasons to maintain this system on his wall (Thread:69258) where he explained me his system. As I already stated there, I have a problem with adding the link to the MYST-N in another place than the MYST-Zulu especially since the MYST-N is still a regular case in Europe.

Suggestion
My suggestions would be to remove any trace of Supply Crates and functional items with random results from |nx= and add them all in |case=. Any Supply Crate listed in |nx= might imply that this Crate guarantees this item since the variable normally contains the prices for direct purchase.

Conclusion
I request to:
 * reserve the variable |nx= (or for GP weapons |cost=) only for actions which guarantee this item such as packages or direct purchase via Black Market
 * reserve the variable |case= for any Supply Crate which currently bears a possibility for this item for any duration or did that until the item was removed.

Vote
I want to limit this vote to 1 month to have an answer till February 10th 2013.
 * stands for: "I support every point of this request." If there is a small point you do not agree with while still accepting the majority of the request, please note that in a short sentence.
