I think you should merge them in a single option, something like "No drop/didn't notice" and put it in the default option (like it already is).

Because in my opinion using this system to register % drops of ships will be not very reliable. Probably people will not report common ships and only rare ones because they are lazy or some other reason. In a way, it is kinda a pain reporting every drop, me myself had to scroll all the ships 2 times to registrer a drop because I missed it the first time and since they are not organized like in the "ship drop" page I don't know where they are.

So, in my opinion. Is this useful to know if a certain ship drops in a node? Yes. And if as you said you plan on adding the battle rank that will make the information more complete.

Is it useful to know the drop rate? probably no because of what I said before.
