Looking for MSK group/help

I’m PL122 and just unlocked the mission. I’ve tried numerous public lobbies and have failed every one. If anyone is willing to help me out, would really appreciate it’s. I am terrible at builds and don’t have the best hardware yet, but I have dual potshots and the de-atomizer 9000/xenon for the crystals. I will help as much as I can. But really would appreciate some help with this bastard lol. Thank you all!!
