Also, people are seriously delusional if you think you really learn how to do any endgame activity, outside of, say... dailies, perhaps, from leveling.
What sort of community are you people playing with where you think people who don't know stuff beyond the basics at the end game aren't going to be treated like total fucking shit by the horrible community?
You basically won't know why you need to cap hit/expertise if you don't go to an external website, and have never done end-game activities before. At best, you could get a grasp of why you'd cap it for stuff that's level 90, but very few people who are new to MMOs are going to know why that even matters or what it means, past that. And, again, they sure as hell aren't going to know what Reforging is.
If anything, this all sounds like a grand scheme by "certain" people to keep "undesirables" away from "their" content, more than anything.
