No, I mean using flares instead of the cart since azurite become a non-issue eventually. That is not to say this isn't easily fixable, my point is more that the league still has major issues and we're at the halfway point. This cannot become a permanent addition to the game without working out many bugs or even just unintended usages.
On top of that, delve is very obtrusive to existing game mechanics. A lot of builds simply suck to play in the mines. I had to give up on my Indigon CI character because he depended on leech for sustain. That's not say the build can't adapt, but requiring a specific Watcher's Eye is a bit much.
Essences, along with some other crafting methods, are quite marginalized with fossils. Personally, I don't give a shit, crafting before fossils sucked a fat dick and fossils are awesome. But you have to objectively realize that they are too powerful and it's not great that they spend development resources effectively cannibalizing existing core mechanics.
Except ghosts. Ghosts can go fuck themselves.
