For Nyx, Ancient Disruptors are harder than any boss or any other mission/content in this game. It makes no sense, and it's all because her energy gets wiped out frequently by the most annoying enemies in the game (Ancient Disruptors). In a game where some Warframes have the ability to wipe out hundreds of enemies with the snap of their fingers, where they can rewind time, create and manipulate alternate realities, and dodge all forms of damage... Nyx, who was one of the most underestimated Warframes in the game, gets completely destroyed by the Ancient Disruptors. The Ancient Disruptor rework should have addressed this, but it didn't and it's ruining the balance between Warframes in this game to a ridiculous degree.
Just make Nyx's Absorb negate Ancient Disruptors, and she'll be back to normal, where she should be. It doesn't make sense that she is crippled so utterly by enemies that are somehow stronger than anything else in the game (to Nyx, at least) because of one broken ability they have.
As a solo player I've learned a lot about Warframes and how to utilize them to complete the most difficult missions by myself (in solo mode where I can pause the game to let my dog out/in). Nyx was very fun to play solo, where I'm able to take the game at my own pace (rather than the preferred breakneck speed of public sessions). My main is Titania because she's the fastest and most powerful Warframe in the game, but sometimes I like to enjoy a slower pace once in a while, and I can't even do that anymore if there are Ancient Disruptors who eliminate Nyx's entire kit.
It's crazy because there are bosses that randomly appear in Steel Path Incursions, those Stalker Acolytes, and they're a complete joke to Nyx. So easy to dispatch, by myself as Nyx, and then Ancient Disruptors come out and are somehow more powerful than the bosses. It doesn't make sense lol
In the infested survival Steel Path Incursion that I was running with Nyx, I spent more time as my Drifter than Nyx because my Warframe kept dying repeatedly whenever her energy ran out. I'm lucky my Drifter is so powerful, apparently more powerful than my Warframe. Absolutely bonkers
Edit: took out double "the"
