Well given this is a troll post it's hardly worth the time but let's actually look at the end game

5 dungeons to earn ToP / ToM - gear progression
4 HM Primal fights for weapons - usefully when vanity comes out but that's about it
Crystal Tower - Vanity / gear progression till you buy i90 or earn coil
Ultima weapon plus Primal EX - i90 accessories + weapon progression
Coil turn 1-5
Behemoth & Odin - Vanity
PvP

It's a decent amount even though in terms of 1.23 we are just now caught up with most of the gear. Still it's far from nothing to do. And since people love to toss XI around like it had all end game content from the start, I would like to point out that it took 3 months after Rise of the Zilart come out before Sky was introduced and seven months after that until Dynamis hit the scene.
