This is entirely a you problem from my perspective. There is no difference in feelings of accomplishment for me between this relic and the ARR or the Shadowbringers relics. The main difference is those force me to do something boring or that I don't want to do to make progress on them, but I can choose to make my own fun with these new ones. I'm not boxed into having to do fate spam over and over whiel watching a movie because I'm bored. I'm not forced to run 180 instances of normal raids that don't even use half my kit because they're from previous expansions. If I want to run content and try to make progress on it I can.
I don't see why there's such a problem with the new ones when there is the freedom to choose what you want to do to fulfil it. If you want to do it the "efficient", but boring way of spamming hunt trains over and over to get tomes quickly, no one is going to stop you, but you chose to meeet the criteria that way.
This whole "earned reward" and "sense of achievement" just seems so weird, it's just being used to try to act like something that was never particularly hard should be harder just to satisfy a sense of rarity for what is by all intents and purposes, a casual catchup weapon that doubles as glam.
