I see your point, and I understand how the game works. I just don't agree with it.
But I like the aesthetics of the game, the outfits and that's mainly why I'm still playing. Glamours are my end game.
I just think that gating everything isn't a good idea. You wanna dye your hair or get a new haircut? Need to do a quest, going to a normal hairdresser isnt an option for some reason
Wanna dye your clothes? Need to do a quest (I guess you need to learn how to do it, but there could be npc that would do it for you instead)
Wanna enter gold saucer? Need to do a quest (I didn't read this quest so I don't know the reason why you need to do a quest for it)
Wanna use glamour prisms? (Need to do a quest, and be level 50, I don't even wanna comment this one.)
And now, new expansion they could make it a new story so that players reaching level 50 could choose if they wanted to do the level 50 main quests or not.
I'm already done with the main quests on my three characters so it doesn't affect me, I just think it hurts new players when they have to do it all while all the other players are doing the new relevant content
