You are correct. I put almost zero value on gold and soul rewards. I do like receiving them, but truth be told, when I need souls I farm challenges. When I need gold I farm PVP. Both are better outputs for these resources.
As for glory, yes, glory is great. I don't devalue glory returns, but I also don't play treasure maps looking for glory. In all honesty, I earn approximately 2000 - 2500 glory per week without trying, just through PVP, login rewards, and tributes (which I collect hourly as often as possible.)
When I play treasure maps it's for a) leisure (I like the design and playstyle of the minigame), b) change of pace (from when I burn out on PVP matches being all the same), and c) farming for gems (and hoping for gem keys).
I acknowledge your fair point that 105 glory is worth 30 pvp battles. 105 glory is not nothing. 105 glory is nice.
But I earn 105 glory just by logging in and checking my income hourly.
Don't get me wrong. If they took the glory rewards away from treasure hunt, I would think that erroneous. But it is not the reason I play treasure maps, and so it is not the reward I look for, nor look at.
On the other hand, I agree with @Razlath and others that taking gold and soul rewards away from high end chests and vaults would be optimal return on time investment.
