I have five 5 alts at end-of-content, plus one post-Endwalker, one in ShB, and one ready to enter ShB.
Having one of the fast mounts (i.e. the cash shop motorcycles) helps.
Having two accounts and two machines helps, too, you can fly a new alt to the Aetherytes and aether currents.
But it's not for everyone.
My alts follow a pattern: level WAR to 60, pickup DNC, level those two to 70, pick up SGE, head for 90 on all three.
Only two of them (my mains) deviate from that -- they did at least one class per role, so I could do all the role-based content.
Road to 80 helps a lot. Especially with getting all the hand and land classes to 90 as well. :)
And it's not totally useless: pairing two alts to do crafting or timed-node gathering saves tons of time.
Of course, it takes tons of time to get to that point, but ... it's time spent playing a game, chillin.
Sometimes I even watch the cutscenes again -- unless Alpha-nerd is in them.
No life? Maybe, but it's worse than you might think.
See, my spouse has two accounts, two machines, and multiple alts at EoC as well.
