So after waiting for about 2 weeks to see the consequence of homogenization

That isn't necessarily the case. The discrepancy between certain jobs now is staggering. A 20% Monk offers more than a 50% Ninja. Let that sink in for a moment. 20% means said Monk either died or has no idea what they're doing, and yet they're still better than a decent Ninja. This becomes even worse between the Casters. A 95% Red Mage is 40 DPS below a 50% Black Mage. That is utterly absurd. Locking out jobs isn't ignorance when there is this wide a gap between them. It can actually be smart. You're simply playing the odds. Sure, you might get an average Black Mage but that's better than an orange Red Mage. Conversely, an average Red Mage is 1,100 rDPS below the aforementioned 50% Black Mage.

Meta isn't the issue here. It's horrendously poor balancing. Your odds of clearing are straight up better taking a Monk over Ninja, and they're better with a Black Mage over a Red Mage. If this were by a small margin, no one would care. Look no further than the tanks. What we're seeing isn't smart margins. Ninja, Bard, Machinist, Dancer, Red Mage and Summoner are several hundreds if not nearly a thousand below the big three. Dragoon, Monk and Black Mage are absolutely dominating.

Thats not even right for all content, just some downtime ones like E1. in E2 Voidwalker a 25th MNK beats a 75th NIN
In E3 the MINIMUM mnk parse is only 100 dps ahead of the NINs 75th.
And in E4 the MINIMUM monk is BETTER than the 75th percentile NIN. its literally crazy right now. Literally the worst monk that ever cleared E4 contributed more than 75% of the NINja's who even MANAGED to clear E4
(e4 min monk is 12.389 rDPS, 75th percentile nin is 12.350 rDPS)

will change in literally one day now tho i hope
