TL;DR: Spamming special counts as heavy attacks, which are fast and can really ramp up bleed ticks
I've been trying out other weapons but I always go back to the shield, the huge arc, stagger, and bleed damage allows me to keep my toughness full, as well as CC packs of elites or specialists.
But after a run where keyboard and scroll wheel didn't allow me to change weapons, I started spamming the special attack with my trusty Rumbler, and I was amazed. I was staggering anything I hit, and apparently it counts as a heavy attack with no windup, so I was rapidly able to apply bleed stacks.
After the match I went to the Psykhanium and tested out how high I could get bleed ticks. Now my loadout
