No that isn't and I dare you to in any way shape or form prove regular chigoes have a -40% att that stacks addivitely with attack downs to the point where you can reduce there dmg to 0 with no buffs just an attack down move. I'll be waiting
I never said that all chigoes necessarily have a -40% atk, but they do hit for less damage than other mobs of their level. Our lessened atk as a chigoe is supposed to simulate this, I'm sure. Again, this is made up for by the fact that they hit faster.

We aren't going to be exactly like monsters in every single way. We don't die immediately to critical hits, for one thing.

Assuming you aren't lieing yet again you clearly weren't awake during it. Otherwise you'd know just how wrong the things you are saying are. Slighlty harder psh. In the time it takes to get those last 10 lvls for the chigoe instinct I have litterally take another monster from 0 to 60.
Maybe you're just no good at being a chigoe

If you really believed that you wouldn't be suggesting avoiding entire mob families all together or just not playing the job.
Why not? Sometimes some people just don't like playing certain jobs. It doesn't necessarily mean anything is wrong with the job.
