I think more veteran players fail to realize that some players will simply use simple attacks, and cantrips for a lot of their playthrough. They won't use the huge variety of spells they have, they won't take advantage of surface effects, or build their character in any sort of proper way, they'll simply do what seems kind of fun, and get frustrated because of it. The difficult is fine for me, but I'm making a dedicated effort to learn and google outside tactics/builds/etc. if someone is simply using what the game shows them, without any previous crpg experience? They could have a very rough time.

Saying "I've played crpgs for 10,000 hours and it's fine for me, so I don't understand what people are saying" is laughable. That's like a professional football quarterback not understanding why people can't throw a spiral.
