Hi @AstemioDaBirra, first of all, thank you for taking the time to write such detailed feedback. I am not part of Funcom’s team but I have a few comments:
I agree with this comment here even though I have never really had issues getting ichor on siptah with all the spiders and spider vaults. I’ve just wanted to point out that crafting oil has been made more accessible now even at early levels as the recipe was added to a T3 alchemist. I am very happy with this change.
I had the same comment. I see an armor and I would expect to get an armor not a candle recipe. However, I have noted that now we get only the newly added recipes from those pedestals instead of old+new library which for me is a nice change as it reduces the rng due to the smaller pool of recipes to draw from.
As a side note: EL still have all recipes in one + they get the voidforge recipes which require eldarium. I am aware that this has been noted and under discussion.
Same but who knows maybe they would add some portal similar to well of skelos as there is something in the middle which looks like that.
I don’t think it is a bug but I agree that it would be nice to see what they do. At the moment, I have no clue what each of them does, I know some one has some poison removal effect and another corruption removal but it would be nice to get some sort of hint about it somewhere 
It does show but it is hidden. I have reported it here.
We do have a shovel. It has been in the game for a long time. It even has a fitting name.
I know there is a set one that I got buffs from. Not sure which one you found.
