I'll still read this since I enjoy even trash tier isekai stories (I only really hate those super gory hero revenge stories where anyone not the main characters is super evil that this one could become but I'm hoping its not.)
But I am getting a bit annoyed by the "certain power is trash" trope. I mean that trope only makes sense in games but in a real world where with hard work and imagination can make use of anything with enough thought or time, it makes no sense for anyone not to be ready for anything.
I mean I can think of a few things an appraiser would be good for even if you could have the guild do it for you back in town. If bag of holdings are hard to come by or expensive it would be worth it to have someone who can tell you what is worth keeping or dropping as you explore. Or they could be good spying, by appraising items and people around them or acting a security by again scanning for anything dangerous being brought near a vip or secure area.
