See, that thing with the other people is what mainly motivates me with MMO's; it's why I stuck with Eve for as long as I did, even if the events were... weekly at best. It's why I liked WoW in the beginning, and why I regretted my decision to follow my one friend from the official servers to the private one - on the official servers, I had only just met people and joined a guild and things were exciting. The lure of 4x XP rates and a free server pulled me over though. IIRC I have like 500 hours in WoW. In there, I got to 70 and was like... now what? A while later I got free time, maybe bought another month and got my character up to 60... but there was nothing and nobody there in the world. WoW's problem is / was that nobody is present in the open areas; everyone below top level or the latest expansion is in the dungeon finder / doing dungeons.
That's what I thought XIV did a lot better - with the fates and endgame content like the zodiac weapons or whatever they were called, all the 'normal' areas remained populated at all times. An MMO needs to feel like an MMO; areas with just a handful of people running around there grinding quests and ignoring anything else because it has no benefits to their goal of leveling up their alts do not feel like an MMO.
ramble.
