Like I said earlier in the thread, this is a result of WOTC's bias and 5e's slow schedules.
As much as 5e's slow schedule is praised, there is a downside.
No Complete Adventurer, Complete Warrior, Ranger Handbook, Primal Power etc is ever created. Wizards of the Coast only focuses on Wizard magic.
Ranger Magic Bard magic, Druid magic, even Cleric and Paladin magic are secondary. So Bards are not getting song spells. And Rangers are not getting new magic arrows, magic blades, new marks, new tracking spells, new beast spells.
In older editions Rangers could cast spells to place trackers, track scents like a dog, summon hunting weapons, or swing from trees like Tarzan.
In 5e, Rangers are sharing reject spells from Wizards, and Druids. Not a single new ranger spell since the PHB.
The problem with D&D since the late 90s has always been the Wizard fanboys taking up all pages in the books.
