If I was to offer an actual QoL suggestion, perhaps they could make the Ixal turn-ins a bit easier for people who want to level a single crafting class. The game seems super unfriendly for those who don't want to omnicraft at early levels.

As for levelling 51+, there are plenty of daily beast tribes, weekly collectables, daily hand-ins and more to level crafters at a respectable pace (I personally feel these all make things far too easy, but that is a different story).

People shouldn't have to google a crafting rotation, this is a symptom of people not spending time to learn the class skills.

As for gathering items locked behind timed nodes, if you're going for the little tick in your crafting logs, there are not a huge volume of items locked behind these nodes. I've done literally everything in the main logs (furniture and master recipes aside) and I barely touched a botanist hidden node (I expect I will probably change my mind on this when I do carpenter furniture!!) and the most I spent at mining nodes were for darksteel ore, gold ore, adamantite ore and raw azurite (the latter 2 spawn every half hour). The only QoL tweak for gathering is maybe a 10-20% GP cost reduction and the increased frequency of ARR nodes.
