Another issue, which I'm not so sure you can blame SE for, is that players are locked into the idea that there is nothing to do before level 75(unless it is mandatory). This is unfortunate as SE has designed a whole lot of content available very early on. Assaults at level 50 and 60 for example.
I beg to differ, more endgame events would entice people to play since FFXI gets a bad rap about camping kings and everyone likes to make light of the issue of '125 people sitting in a zone for 3hours waiting for something to pop' versus WoWs majorly raid/instanced endgame events. I know alot of people who have quit based on the fact that endgame FFXI has less to do with challenges or having fun and more about who can get the mob that spawns purple. The endgame mobs are a joke to most people that get past the 'virgin' fight against them and the addition of the ToAU HNMs did nothing beyond increasing the clock on how hard they spawned.
SE has already moved focus away from HNMs and apparently seem to make them entirely
optional(compared to the RotZ scene most players were introduced to). Adding gear progression doesn't mean fixing HNMs and most of that information is probably coming from people who haven't played in a long time, meaning new things wouldn't change their mind(in the case of Limbus, Salvage, and Assaults).
