Group instanced content is where the challenge in PvE is nowadays. I don't think planned new solo zones like Wrothgar are going to change that one bit... there would just be too many people complaining if there's some part of it that's not easily doable, as has happened before.
Only advice I can give you is that you might want to try group PvE some time if you want an actual challenge. I don't see much point in handicapping yourself just to have some degree of fun
Welcome to what I call the Baby Generation.
It's not just in video games, it's everywhere. People expect to just chat on their damn cell phones at work all day and get paid for it.
As Louis CK says, this is literally the worst generation of self-entitled d-bags in human history.
