What I keep saying and people ignore it to attack straw men:
First, speaking in generalizations is necessary. Yes, there are people out there who have maybe never lost to a DE team. That doesn’t mean there aren’t an awful lot of people who have. So one guy posting two videos doesn’t really prove anything that hasn’t been said. I beat DE teams all the time. But.
How one loses or wins matters a lot.
We (generally) like it if we get a turn 1 or turn 2 win where the AI doesn’t have a chance from the first move. Even the people who don’t like that want to play a game where they have a team with a plan that is executed.
We (generally) don’t like it if the CPU defeats us before turn 4, especially if our defeat comes from a large cascade.
The problem with every team that has been nerfed so far has never been that it was undefeatable. It was always that it was too reliable. For example, the Psion/Rag/Famine/* team was once a menace. It led the developers to create several new immunities to mana drain/burn. Now the team is still powerful, but one can build teams immune to its threat that win more reliably than others.
Could we beat Psion before that? Sure. But it wasn’t fun.
That’s the heart of the argument. DE is “not fun”. It has a relatively low chance of a crushing defeat. But when it does that it’s because it wins dice rolls in a way that is upsetting.
That’s fun if you are the person using DE. That’s why people want to keep it in Delves. There it’s pretty fun. It’s not so fun in PvP (nor are any of the meta teams, for that matter). When it wins it does so in a way that leaves you no options. When it loses, it can be a slog as the 4+ minute video above shows.
There wasn’t a counter for Wisp, and it was nerfed. There wasn’t a counter for Kraken/Mab, and it was nerfed. There wasn’t a counter for Nyxbringer and it not only got 3 separate nerfs, the devs also nerfed the Mana Surge and cluster calculation mechanics specifically to stop it. Divines’ only counter was itself, and 3 troops plus Mana Surge were nerfed.
DE doesn’t have a counter. It deserves a place amongst the other teams that weren’t fun to face. But the nerf isn’t going to be simple, because it’s cool on offense and I think even the people that’d like to see a nerf don’t want to lose that.
This is not a simple problem that will require a minor adjustment. It’s also not a case of people wanting a 100% win ratio, no matter how hard you try to steer the conversation that way.
It’s about wanting to lose to teams that make you feel like you made some bad decisions and could’ve won if you got another chance. AKA we’d like the illusion that these games aren’t decided by luck, and we hate teams that break the illusion.
DE is analogous to Goblins in that respect. Goblins is easy to beat, but every now and then you get that one perfect Goblins board that lets them destroy you on their first move. The argument is and always has been DE gets “that perfect board” a little too often.
