Getting pretty lazy on collections

I thought the jungle treasures were passable, though they were just recoloring the same few models. But at least you could easily tell them apart. But the Sulani ones...I mean, seriously, 18 treasures and only three models, some barely tinted differently? I wonder just how many different sorts of sunken treasure there are; how about some silver, gold, and platinum, etc, ingots? They would have been cool to keep, no matter how many of the same kind you got (fill that vault with gold bars). Or some chalices or swords, or something. Point is, collecting should be more interesting than just doing it because you're compelled to complete everything. Do really like the underwater photos, though.
