FFXI isn't time intensive, I don't know what your getting this from, Gear doesn't become useless after three months like XIV, I would actually say FFXIV is more like the game that doesn't respect your time
- you have to play "Catch-up" just to be where everyone else is at, going though dungeons and MSQ just to get through the Next Patch/ Expansion
while in FFXI, once you become level 99 which isn't hard, you can do stuff like Abuscade or Unity NMs ( Notorious Monsters)
in FFXI, once you get thought your nation missions, you can start on any expansion that you like, and once you do that expansion (like Chains of Promitha or Seekers of Adoulin) More endgame stuff opens.
like I said, gear doesn't become irrelevant once you go past certain levels, some of them are BiS still
like the Rajas ring, still very useful at 99 even if thought it's a level 30 ring
best ring, it's very low chance and RNG but one of the best you can get.
so I would say FFXIV is a game that doesn't respect your time, while in FFXI, you can take a long break and your gear will be fine, won't have to slog and a very long and boring MSQ just to reach the next expansion and you won't have to play catch up to do endgame stuff with your friends
