May I remind you that
a. Lore Masters had been tedious to play for a long time (after the Wastes) because they had weak pets and at best moderate staple attacks, with the better ones being gated behind an unbearable cooldown timer (up to literally three minutes), and
b. pets do no longer auto attack, due to some botting raids that ruined the game since East Rohan?
This class is not easy. It is only overpowered. By now. It may well happen that the lore masters get nerfed. Again. They had done it before, after the Wastes.
The worst thing about it was that Mordor is tightly packed with mobs, so there is no safe distance from which you might send your pet in. You would try to circumvent the more difficult ones (with difficult I don't mean Elites, I mean Signatures), but then you ran the risk that you were running straight into the next one. Or, while a fight was drawing on (it was so slow that I cannot even describe it), other mobs nearby would wander more closely, notice your presence and start to attack. And Lore Masters don't wear heavy armour. I still wonder how mine made it through.
As others have already said, if you are in favour of a higher difficulty, there is that NPC in the starter areas that you can ask to increase it. So why do you complain about the game being too easy?
