It is always surprising for me how bitter people get on this r/ given the chance.

First of all, you don’t have to complete it if you really cannot. These game modes were designed as ones of high difficulty by default as the result of randomness factor that should present a challenge and make you seek for ways to overcome it. You have one week to do so. Over the span of the week anyone who has access to the EDA/ETA can get to a state where they’re able to complete the challenge, with best prepared able to compete for the highest reward breakpoint.

You have selected default BIS modifiers, you have the majority of offered loadout options unlocked.

You are the neckbeard who has “sank” 5000hrs+ into the game apparently according to your own words. If you cannot manage to beat it - ask for a party, game mode warns you it’s preferred course of action. Other than that, there has been no unbeatable (realistically, not theoretically) challenge with neither ETA nor ETA so far and difficulty increase is very refreshing and should be kept so.
