It doesn't matter if people FATE with you or not so complaining about no one else FATEing isn't an excuse really. Even if you are the only one doing a FATE you can clear them easy. And if no one else is doing FATEs it means that the FATEs have gotten easier to complete. Go to the areas you listed and do the FATEs alone if leveling up alts means so much to you. If you've given up on Leveling roulette because of the so called "2 hour queues", then you can use your Chocobo as well and clearing FATEs will be extremely easy. Even boss FATEs as a DPS with a Chocobo out will take 3-7 minutes solo.

I highly doubt the Duty queues are as bad as you say it is. Just queue up and alt tab with game sound on if you hate waiting around for a pop. Even if it takes 2 hours to get into a dungeon, it's very easy to level up once thanks to killing mobs in dungeons and close to once more with Duty Roulette bonus. Clear some challenge logs as well and you will gain 2-3 levels from 1 dungeon run.
