Warrior/Knight Help Collapse Warrior Build - Need Assistance

Hi I'm a lvl 104 paladin warrior and I want to make a good build for finding mythics during lootruns. I currently have the mythic collapse and would like to make the build around it. I am a paladin warrior but I can change that easily. I have around a stack of LE I can spend. Additionally, I have completed the Hive if there are any suggested loot items from that quest. Thank you very much for your help.
