I completed all of them on mayhem 1, they are not as bad as this post may seem. The big thing is having all level 50 gear and making sure that you utilize your skills in the best way. Most times in these trials it comes down to damage output and having the right weapons, so I recommend waiting till 50 and farming a bit before the trials as it’ll make it much easier. If the character OP is playing is Zane I may be able to understand. It is definitely doable with other characters though with out of the remaining 3 Moze having the hardest time maybe.

Still small things like that make an enormous difference. When you end up doing it I wish you the best of luck!
