This idea isn't new - I proposed it in 2015. It's great how some things periodically return, which is, especially in Edain, completely normal.
My arguments were from gameplay perspective:
When you give all gifts to heroes, that ability become useless and only occupies hero's slot and do nothing. It's the same like Sauron's influence. But in Mordor's case you at least have many buildings where you can cast it.
When Gifts of Lorien ability was announced, nine heroes could receive gift:
Level 7: Gifts of Lorien - Galadriel hands gifts from Lothlorien to a hero.
Thranduil: Gets +15% armor and commands two rows of Palace Guards with his 'Shield-Wall'-Skill.
Legolas: Gets Galadriel's bow which enhances his 'Hawk Strike' and 'Arrow Wind' effectively.
Tauriel: Is permanently capable of wielding her daggers and being protected by guards.
Haldir: Gets a white arrow instead of his golden arrow which will stun all units in wide radius.
Celeborn: Gets a royal armor that improves his defense and attack by +10%.
Rumil & Orophin: Get mighty elven armor that highly enhance their defense but lowers their speed.
Frodo: Gets Earendil's Light which is a light to him in darkest hours.
Sam: Gets the seeds of the golden wood.
But later, Tauriel was removed and implemented only via spellbook, so in total 8 heroes could receive that upgrade.
Then I stepped in and said that there is also Grimbeorn, only hero who doesn't have possibility receive gift (except Ents).
But argument against was something like that Grimbeorn would probably reject the gift, which is quite weak argument and goes even against lore, because we know that even Gimli, such elven hater, accepted gift from lady and protected three golden hairs like the greatest treasure in the world.
Grimbeorn fits to forest, like elves from Woodland realms, probably was in contact with them. But mainly - in Edain he fights for lady in Lothlorien faction, so gift from her would be obvious choice how to appreciate his efort.
In the upcoming patch, even Frodo and Sam will be removed, so only six heroes can receive gift:
- Rank 3: Gifts of Lorien. Target hero receives a precious gift, allowing Galadriel to reach him with her abilities.
* Orophin and Rumil: Elven armor that drastically increases their defenses.
* Haldir: Blessed Arrow with more damage and a larger radius than Radiant Arrow
* Celeborn: Lordly armor that increases defences and damage
* Thranduil: Royal armor and an additional row of Palace Guards for his shield wall
* Legolas: Bow of the Galadhrim that increases damage of Hawk Strike and Arrow Wind
My argument about uselessness of that slot became even more relevant.

So definitely this thread has my support!
