New World will replace FFXIV when it eventually launches later this year, atleast for some time. After that we are probably getting close to a 9.2 release in wow and maybe we know more about the next xpac. These things tend to shift, as is normal. I remember back in the "old days" with gw2, swtor, rift++ were people left wow behind "for good" only for most people to return at a later stage.
Its really up to Blizzard now, cause people will return if they deliver. No MMORPG can hold people away from wow if Blizzard delivers quality again.

1 - Yeah, right now people are so hung up on hating wow that no one looks at FFXIVs issues. Yet.
2 - The community is a tricky one. In FFXIV you can play most of the game(Story/leveling) without much(if any) interaction with anyone, neither good or bad. Same with ESO, a game I play now. I can slog along doing alot of stuff(even dungeons) without uttering a word with anyone and it all goes smooth. Does that make it a good/bad community? As with any online game, finding like minded people is the key, but can also be very difficult. Especially if you dont have friends to take along. Funnily enough, i've been having a great time doing m+ the last couple of weeks in wow since m+ was introduced in wow. I've stayed away from it cause it was so toxic, but decided to give it another shot. Since then I have mostly met nice people that knows what to do and are willing to have patience and communicate. Its like the toxic people vanished and nice people are left. But thats just my experience, might be a isolated one.
3 - Asmon is a smart man and also he realised wow was in a serious all time low, while FFXIV was gaining traction. He and all his close friends now stream that game alot. It works for now and in a little over a month New World launches, hopefully(!). New World, FFXIV(less), Classic BC raids(less) & 9.2 will carry content the next year.
