I feel like you would have gotten much better responses if you didn’t come off so…brash…sarcastic…hostile…and sort of rude, honestly. If this entire thing was reworded with a bit more respect for the Devs and other players, and not laced with sarcasm, I think that perhaps people would listen to what you’re saying.
With that said, I do agree that the rewards for higher difficulties does not scale with how hard the battle is…it is not worth the time invested to play on those difficulties.
Rather than bash the game - that people really enjoy, hence they are on the forums - you could have made a proposition to buff the payout for higher difficulties and stated your reasons respectfully.
As others have stated, Explore mode is really awesome when you don’t want to wait for your Arcanes. I was hoping for something like this for a long time because I get bored of just waiting for the right week to come (especially when I’ve been wanting to trait Mercy for the past month and a halfish). With the update I was actually able to target the swamps I had without draining myself out. I had attempted to farm challenge mode in the past, but all it did was annoy me. I absolutely hate going against the exact same team over and over again. And the drop rates were abysmal. Now they actually feel good! Like you can get what you are looking for if you invest the time required. Explore mode has breathed new life into this game for me, and I feel like it was a much needed addition!
Personally, I like that PvP is for gold, and you can also get 60 souls per battle if you use Valkyrie…and I like that Explore is for trait stones and soul farming. The PvP matches are a lot longer than farming explore mode. And if you are playing explore mode, you might not want to be on the highest difficulty because you’d want the battles to be fast so you can be efficient with getting your souls and trait stones. I like to play on Hard because the battles are quick and you can get your 70 souls and keep going at a great pace. The rate of getting souls is much higher on Explore mode if you play at easier difficulties vs PvP, based on speed and you can get more souls per battle.
If you are playing for the challenge versus the rewards, then obviously play at a higher difficulty. Personally, I like to steamroll through everything. It feels satisfying, I’m not sure why 
And Treasure hunting has actually been a very great tool for me! I use it when I need Glory, since it seems to be faster than farming out PvP battles (especially while Mab is broken for iPhone - I have had a lot of struggles without my freezing and I’m having issues with finding another team comp that I like and is successful. I wish that I had the mythics!). Plus I remember the hunts being useful at a really low level. But, basically, as a level 300ish player I use the treasure hunts when I need a good burst of glory. My reserves have been drained and I’ve been eating up my 4000+ glory every week as I get it, but I’m finding it hard to stock it back up because every week I need the trait stones…I digress.
Challenge mode is great for completing the first time for the burst of souls, very helpful in the beginning.
Questing is great to unlock the end rewards and get your class (although I rarely use a class because I’d rather use my troops).
Every feature in the game has its purpose, even if you do not see it or want to utilize it/need it…the purpose is there. Of course there is always room for balancing and improving areas, which is what we need to focus on. This game is not complete garbage and it is not boring for its solid player base. As with almost any game, there will be people who get bored after a few months…but I have been playing for 4 months now, I think? I have yet to get bored. There’s still so much that I want to accomplish. This game has a lot of things to do, and a lot of ways that you can enjoy it.
