No, endgame is not just for the 'hardcore' players. The little endgame that FFXIV has now is challenging, as it has been designed to be. As I outlined in my previous post, the ideas behind the difficulty of events such as the Ifrit fight is that between each major patch the entire range of players ends up beating it. He said that the ideal progression is that the hardcore players beat it first and the casual players end up beating it later when the mechanics of the fight become well known and it becomes easier.
It doesn't take a hardcore gamer to be competent and complete difficult endgame content, a casual player can be just as good. FFXI is a very clear indicator of a system that worked, it had a large range of endgame events (that will be the case for FFXIV too later on) that catered to a range of players. When salvage came out it was hard as shit, a couple months later you had the right party setups down, the right strategies and paths to follow and it was easy, easy enough for pickup groups.
It devalues the victory of ALL players to allow a difficulty setting for endgame content. Where's the satisfaction of watching a cutscene for beating a mission fight when you do it on easy mode? When you watch a huge-ass monster die in front of you, how do you feel knowing that you made it easier for yourself? This isn't pre-school, you aren't having your hand held, either do it properly or don't even try.
I seriously think all of the people in this thread crying to have this implemented are a) jealous of more skilled players that have done things like beat ifrit, b) had their application to a good linkshell denied or c) are just plain lazy and want things handed to them like children. You aren't here to have things made easy for you, the point of the game is to have challenging events that you work towards, and the satisfaction of completing them AS THEY ARE is the feeling you strive to have.
Your analogy is garbage btw.
