I noticed after a silly Demon Wall wipe yesterday that it's easily possible to run from the boss#1 checkpoint all the way to Demon Wall without pulling agro on a single monster. So, aside from the statues that poof into monster-form and auto-agro someone, you can skip, dance and frolic your way through half of this dungeon without pulling a single monster. If SE really cared all that much about all of the trash being killed, I imagine they'd make it slightly more difficult than it currently is to get past them.
