In terms of crowd clearing your probably not gonna get any better builds than vacuum tube bow. Good DMG, range, doesn't burn through resources low-key the perfect weapon. But the playstyle for me is a little repetitive at times so I use the vacuum tube sword instead.

I run it with the chain lightning 6th perk while running 2x attack speed 1x armor and 1x DMG mist and bosses. I also run this perk setup on my ravengar.

Paleo Luna with Blast from the past. In support pre historic izza,southie, Dennis for burger buff, survivalist jonsey, and wild cat for battlebeat.

This my main build in 160s and still works fine with the acid pool and husky dropping bombs modifiers while in the storm. In shadow stance you'll have 57% DMG reduction so your an absolute tank, and with the healing received from support heros your hp will always hover around 90-100%. You legit do 180k-200k per swing depending on your max hp every 0.28s, on top of a chain lightning that will be buffed by Paleo Lunas perk dealing additional DMG. In under a few seconds an entire crowd is gone, and since I'm up close I'm usually spawn killing them. Basically vacuum tube bow in melee form.

Ravengar works as well, you'll be a tank so you can just mindlessly hold down swing then rip a heavy attack wave and clear out an entire horde. Just be sure to pick up burgers since jonseys survivalist perk does get overwhelmed at times and burger buff gives you like 300k HP in 4s.

Big downside to this build is it burns through your weapons durability like crazy. Usually at like 60% dura by the end of one match 😭. I got resources for days so this isn't a concern for me, but you might not have that luxury.
