You and others may find the gameplay unfun or not engaging for Archies. But I absolutely do.
Challenge is something that does not exist in Warframe. Challenge has left this game long, long ago. The only "challenge" is self-imposed limitations, or an unfortunately chronic amount of stupidity. Things are all made pretty straight forward, and the tools to succeed are thrown at a player like confetti. It's easy to pick the right tools for the right job everywhere else.
And suddenly, that's gone. Suddenly, players have to think. Players have to coordinate. While I have a frame that will carry us in this mission, a friend of mine will have one that can dominate the next... if it weren't for a certain modifier. But this other frame he has, if we use it with my second choice, can easily do both together. Suddenly, I'm thinking of workarounds. Suddenly, coordination has returned to Warframe. It has enough of a chance to be harder to do even as an end game player where you're rewarded for just... coordinating with another person in a healthy way.
But I also recognize that players are generally entitled and toxic. They want to have the winning play, rather than it be a team effort more often than not. They wanna be the leader, barking orders at others while someone barks orders at them, too. There are downsides to having something that encourages coordination, but it's always important to remember: Not everything is for everyone.
As a long time player, I am also rewarded for my commitment in Archies. Every frame and weapon offered to me, I have forma'd already. This is also a big part of why I like Duviri. You have seven days to do the weekly, so you're given time to prepare the gear you're offered as well if you haven't come as far. I feel as though the game is meeting me in a fair middle ground, where it's asking me to put what I have ready to the test, how good my knowledge is of meta, especially team composition.
That kind of feeling of validation is also woefully absent in Warframe, much like challenge itself. I know my frames, what they're good at, what they can do together, and rarely is that knowledge flexed. While Elite Archies are maybe the hardest content in game, I wouldn't say it's hard still, but for the first time in years, I actually feel challenged; to flex my knowledge, my adaptability, in a more hostile environment, a different environment even. Suddenly I don't have my Operator? Then I need to know what I'm doing with my frame a lot more.
Or, in a lot less words... I have to put in some effort for the first time in maybe 10 years. I enjoy the coordinating, the details and fine points of selecting gear, overcoming different limitations, because I can flex and do that.
I enjoy Archies greatly as they are as a long time and very overpowered player. And not just that, I'm also handsomely rewarded. I still need a lot more Archon Shards.
However, I'm not opposed to more fun modifiers either. Stupid things that make no sense but benefit the player, such as all ragdolled enemies always clump onto upright enemies. The player gets more damage out of it, and it's just funny to see, too.

Edit: And just as an aside, if you're trying to discredit players as "randomizer adepts", or in human terms, someone who put more time into the game than you, for... having put more time into the game than you, that doesn't make you right, you're just finding a nonsensical excuse to put down entirely valid criticism that is from a different view point than your own because it's from a different viewpoint than your own.
I can say with confidence, this game mode is definitely not for you if the downside is preparation. Archies is the alternative for getting more than what Netracells offers. The player choice is to engage with it or not and simply do Netracells instead.
The world won't be handed to you on a silver platter, nor is that what people want exclusively from games. The reason Souls games are so popular is because you have to earn your victories, and if you just dismiss anyone because they like Souls, then you deserve to be gatekept.
"Everyone having fun is just pretending to" is completely toxic and doesn't belong on any game.
