Since you can upgrade heroic -> epic -> legendary there is "bad luck protection". The only disadvantage is that the gear is lvl 30 not 29.
If you ransack the legendary chest you can just get an alt, can even be a low level, to speed run heroic and then upgrade it. Hay is really no problem with the explorer chests. Star fragments are rarer but you are guaranteed 5 or the saga, enough for one item.
Also there are no super long quests with 5-6 items (looking at you "Just Business" or "Toxic Treatment"). It's all 3 to 4 items, which makes it easier to get a specific item. And only really Danger at Dunwater is still long, even if you do the shortest possible path.
Artifacts are pretty easy to get too. Because there are many explorer chests and good drop rate from Saga.
Wish gear from other packs wasn't so hard to obtain. I Hope SSG can apply "bad luck protection" for other packs/expansion packs too. Either like Saltmarsh with upgrading, or a different system like collectable turnins.
