There was no winning move here.
Dragon’s Eye was a bad situation that the devs should’ve handled months ago. It would’ve been perfectly acceptable to remove the item from the game until it could be reworked, because it completely broke their design for a challenging game mode.
Instead, they tried to do the right thing and made a small nerf. That small nerf was hailed as something that would make it useless, I saw plenty of rent garments in response. Then people figured out it was still pretty powerful for Delve and moved on. Then people figured out that, combined with some new troops, the weapon upgrade system, and the hero class updates, it made a fabulously annoying troll defense for PvP and GW.
So let’s be clear: because the devs decided to be “nice” to players, they made it worse. Dragon’s Eye was only a tiny bit less effective for Delve, but also went from “somewhat useless” in PvP/GW to “an effective defense”. To be fair, if you take away weapon upgrades, or you take away some cheap brown-generating troops, or you take away the Stealthy and Backup hero talents, all of this falls apart. It’s still great for Delve and it goes back to “useless” in PvP.
But the initial problem from the dev perspective was that the weapon trivialized Delve. So it’s logical the devs aren’t going to make a move against it that doesn’t also dramatically change its significance for Delve.
That is to say: they put Dragon’s Eye back where it was. I think it’s actually more interesting than it used to be, but “interesting” need not mean “powerful”. It’s no longer as large a threat to PvP/GW, and Delvers now have to approach their problems differently.
It is never a good thing when there is one solution to every problem in a game like this. This is a game that asks you to spend years, not months and is not ashamed of that. So I cannot feel sympathy for people who are upset that they can’t beat its highest-challenge mode in weeks.
The devs have hinted they aren’t happy with the challenge level of Delve. When they are not happy with stuff, it changes. The devs are also very slow to change things. So maybe put some big kid pants on, collaborate on non-DE teams for Delve, and wait a few months to see what the devs come up with.
