XI players really have selective memory when it comes to crap.

Lets look at COP,

Positive - great story, few cool looking mobs, some interesting BC's that required teamwork

Negatives - extremely long cool downs (even if you failed a BC usually had to wait for 2h to reset), ENM reset and very long trigger quest, Tiamat repop extremely long, Vrtra and Jorm drops usless, tons more NMs with stupid pop times (like astral earring NM), Jailers extremely low drop rates (remember when triggers were not 100%? fun yeah)

Players now do not have patience for doing stuff for hours upon hours for a chance at a simple thing. Game needs to be more accessible to players who have 2-3 h to log on and play and not high school kids who can play for 12 hours a day. XI in COP era was a full time job.
