I totally agree with OP, but I also would like to add my own two cents. The maze of tomestone vendors, wondrous sundries, and upgrade items is unreasonably complex for people trying to rush to end game. There are a lot of new players who aren't going to be aware of how to get poetics, or how to upgrade the right gear, because unless you've been in FFXIV the entire time, riding the community wave, the upgrade system and the vendors are confusing and disorganized.

Yes, it's easy enough to learn it, and easy enough to ask for help, but you shouldn't have to have a tutorial to pick up current gear from a vendor and upgrade it. It's going to be funny when new players join during Shadowbringers and have to tromp their way through Rhalgr's Reach's maze of upgrades. I still sometimes forget which desk to go to in order to find what. It's really needlessly confusing, with badly labelled sections. A newbie would never guess "Wondrous Sundries" contains a bunch of upgrade items. It sounds like it contains crafting items.
