Yep, took me a while to even know about this one until I saw an old post about it. I like that devs hid a stash of treasure like this on 2 separate islands (the other one in Conundrum Rocks), I hope they do this on other islands as well. Not necessarily on all islands, but preferably more than 2. :) Example, what if they added a stash of Chests on top of that huge tower at the Phaelanx Forge in The Blazeworks? The Aether Jet up there is fun to use, but a little extra reward after being able to get up there (which is a bit tricky) would be nice.
