Gold hoarder voyages

I'm getting pi***d of by the voyages i'm getting from lvl 75 gold hoarder, I always get like 8 different islands with only 1 or 2 treasures on one island (of course, not even captain chests).. I think those high level voyages needs to be get some kind of buff, there should be less islands with more and higher quality chests.. Please consider remaking those high level voyages.. I heard more people saying it's not worth to be doing high level voyages and it's better to get someone with lvl 10 and do his voyages because it's a lot faster and sometimes, even with better loot
