Looks like the 5th edition rules aren't that great after all. I don't know who made them and why, but would be useful to have a sticky post somewhere here with those rules, and a very detailed explanation of why everything is like that.
I never heard of any of these before, so no comments beyond that these should be clarified right on this site for people like the OP.
There are many reasons for frustration, and understanding why things are how they are can go a long way.
