Honestly guys. The problem with monsters that suck is we can't actually identify what's wrong.
When things are too hard, it's easy to say why. This system is rubbish, that specific maneuver doesn't do well, etc. When it's all too easy, you don't need anything but your basic attack. Everything else is wasted and it's impossible to get any real gameplay evidence that something is borked.
Basically I can't playtest this system properly with the mobs this easy. I've started to double all the HP values of all the monsters and that's given me a little bit more, but the accuracy is weird too. ACs on the higher end are far, far too low.
Can we just crank up the diff and make this big weepy eyed puppy into a dire wolf with chainsaws for teeth? Then we'll really be able to tell you what's underperforming.
