Assuming there is no repeats, there will be 3-4 backgrounds that cover every 2 stats stats combo.
Sure - but that's assuming no repeats and an even distribution, but more importantly, I'm talking about the Skills and Feat.
A bunch of Feats aren't "general purpose" - i.e. they're either bad or only suitable for some characters. Some may even be literally useless - "lightly armoured" is useless to what, 9 out of 12 classes? 10 out of 12? If a Background has that, few will want it. If it has certain stats associated with it, something very close to 100% of PCs will not want it.
Then you have Skills - if they Skills don't line up really well with the Feats and/or aren't general "adventuring skills" (and really, some aren't), people are not going to want that Background.
But I guarantee certain classes will have a Background which has their primary stat, CON and/or DEX (or both!), two skills which work well for that class, and a Feat that works well for that class, and like 70-80% of people playing that class will thus pick that background. And it may be a hilariously inappropriate Background. We can already see Acolyte is a bad pick for virtually all Clerics and Druids, which is pretty funny.
Yeah, there will be multiple optimal options for every case it seems, which is a far sight better than Rave/Class combos in the 2014 PHB.
And far, far worse than Tasha's, which most people have been using for 5 years. So that's a nonsense comparison.
Anyway, I'm going to be laughing when the real choices are here, and one of you guys defending them and claiming your players are god's perfect
himbos non-min-maxers is like "Omg why does every Cleric always pick Guide and never Acolyte?! Why are players so dumb?!".
