Terracore questing...is it really worth the hussle?

I must say I feel cheated a bit. Of course nobody has made any promises, but my expectations were based on my first time. Isn't that the exact opposite of how it works in the real world? Hue hue hue 😂 The second time I approached questing with high hopes of more loot than the last one. I upgraded all my stats at least once, after all. The reality was more of a cold shower in the winter than of pleasant experience.
Please find below attached the results of the first and the second attempt and please do notice the difference in loot. The obtained amount of relics looted is unacceptable considering the cost.
I don't know if I should ever try questing again if the results are to be the same. This is wrong.

I need to reconsider my whole perspective and strategy. Now I think I should only focus on upgrading stats only or I dont know. The only good thing that occurred was I passed @deepresearch in leaderboard
