You sir have balls of steel
And to the people saying DE can't add hard content into the game because people complain it's too hard:
That's not true. The real problem is that DE's definition of difficulty is completely out of touch with how the game is played. To them hard content is simply giving enemies a ton of CC, removing effectiveness from abilities and players' resources and straight up deleting certain warframes/strategies from the supposed "endgame", which always culminates in a cheesy, unfun meta that is incredibly frustrating for players who would like to play something else.
Personally, the beginning of fixing endgame in my opinion should be removing every cc immunity so that i can actually play Nyx without relying on my teammates to kill them or abusing Assimilate to avoid getting one shot. Just make enemies have diminishing returns, ya know, like it always was until they decided to change their formula for no reason. The corpus also need various adjustments/bug fixes one of them being the ridiculous vertical range of sappings, being impossible to see on the bottom of a downwards slope but still damaging you as you jump from the top of the slope. This is one person's opinion, i'm pretty sure people all around this game have similar complaints on their own preferred playstyle.

TL;DR this all basically boils down to: DE's concept of difficulty is unfun, frustrating and often uncounterable unless you follow the meta, which is not what players want so of course they will complain.
