To briefly touch on the video series, I think it is important to consider that the players of FFXIV are of a mostly adult or late teen audience
Funny, thats not what you said here

While I admittedly haven't had the time to read each post in this thread, I just wanted to chime in and say that I'm not sure that making MSQ content easier in order to not exclude older players is a good thing. Why would someone in their late teens or early 20s want to play a game that was also designed to accommodate for the reaction times of someone significantly older? I do think that having a set target demographic in terms of age is a good thing, especially in terms of difficulty level.
