Personally I found the end bosses of the very first dungeon in EW a little bit challenging and was worried a lot of people might cry it's too difficult. The first trial is also pretty intense too for anyone not able to visualize in 4 dimensions. P3S is far too harsh imo, I haven't to this day found a PF that is able to get beyond the first set of adds and everyone else demands practice from FoF onwards, like how am I supposed to do that when nobody else can get to that stage? The rest of the content though is fairly decent, I think a little of it is braindead and that may be for casual players who just want to chill and don't want to think too hard what to do. Let's not forget this is an MMO that has content of varying degrees of difficulty to cater for different types of players, not the Blade of Souls types who have to muscle memory everything and pre-emptively time each mechanic to the millisecond. If FFXIV went so difficult that every fight was an extreme test of will and reflexes I'd quit it, I don't want a game to stress me out like that.
