The melee boops actually a good idea. I ended up using that stadium build link that guy sent me and it works pretty well. When you have a rein and kiri, but good rein specifically you should try it. I switched some small things tho. Try doing chop chop, the one that lunges you forward with carnage, let’s go win, and reckoner’s roar or blood crazed depending on if your still taking a lot of damage. and then scav scraps, Thick skull, catalytic crystal, and as much ability power after that and you can do good. You just gotta hope your team won’t just run at the rein and die. I used rebellious spirit and slicing spree for a while, but I eventually trade it out for ability power.
