After many failed solo queue attempts with randoms and roughly 60mil lost, I finally could complete the Gauntlet missions and unlocked the premium insured slot by doing the Building 21 mission. It was hard AF because of factors such as my McDonalds internet, lack of experience on B21 itself and having absolutely no clue how to do the mission in the first place.
Very special thanks to "RoscaMuerta<3" who carried the match, saved me and even retrieved my armor (besides extracting with the Kui Ji weapons case).
Now I'm 0.0000000000000000001% less hot garbage in B21. ðŸ¤
Anyway, now I can go back to loot goblin'ing in Serpent Island. 😎
To those who are struggling like I did big time, keep throwing yourself mindlessly at that mission and you'll complete it eventually! You are bound to have a once in a blue moon chance like I just had and at that moment everything will be in your favor to complete the B21 Gauntlet mission and the others as well. The premium insured slot is more than worth all the pain and frustration. LOL.
