I hate weeklies, not because they limit progression but because they take so long to finish.
It takes FOREVER to finish WT, the 3 Mhaci raids, etc. when all I want is to finish leveling my crafters and maybe FSH. I also still haven't finished Sephirot ex, despite having cleared every other EX primal and having them predominantly on farm now, with Zurvan weapons on the majority of my classes, excluding MNK and WHM whom have their completed animas.

Also, the loot limit vs the fatigue system debate is also ludicrous. Unlike the loot limit, the fatigue system had no play around at all. Sure, you could play around with different classes to level them in the fatigue system but considering that some people just dislike other classes for one reason or another (I despise Tank classes, BLM, AST and MCH) that being forced to play them for any sense of progression is just as bad as no progression at all IMO, whereas the loot system can be all together circumvented by crafting. Also, considering how much gear is shared one way or another between classes, it's not even as limiting as it's being made to seem. Tanks, healers, casters, and support classes all share gear with NIN sharing jewelry with Support and MNK and DRG share jewelry with each other so it's not as though the gear limit is as crippling as it seems since, while the same gear might not be BIS for each class, it's still largely acceptable gear for any and all content.
