I expect it's not in the scope of the current rework, but what's by far the biggest pain point for me right now is that you can't actually work towards your chosen victory path until modern age. The up-to-six tokens don't really make tangible difference, since three out of the four are still linked to your production, and the economy one is bundled with your diplomacy, but also, gives you a discount from something you can always afford anyway if you have a strong economy game.
In Civs 1-6 you could have a domination game all the way from the start, or a science game, or a culture game, or a religion game. In VII, we just spend antiquity and exploration building generically strong empires. That's why the legacies feel samey, that's why we are all doing some occasional meta-gaming with delaying a legacy path. I'd like to see antiquity and exploration victories, sure, but the main thing history-in-layers needs is for the bottom two layers to help us work towards a win that ties to their legacy.
Each settlement conquered in antiquity and exploration should give us 1 progress point on the modern military legacy. Each civilization wiped out completely (in any of the three eras) should give us 5 - and the tracker should be 40 instead of 20. Skip projects at the end.
Each antiquity wonder should become a single-slot museum of itself in modern. Each 5 slotted exploration relics should turn into a single artifact in modern. And the overall target becomes 25 instead of 15.
That would give a strong incentive to just go ham on religion, or on conquering, and worry less about a game of whack-a-mole with the objectives. It's why science actually feels sort of okay now - you just generate lots of science, and research lots of future technologies, which gives you modern era technology boosts and lets you reach the projects quicker, whereas playing for a culture win is just twiddling your thumbs a lot and playing for a military win is building a big army but not actually conquering too much with it, because then you have less you can conquer in modern.
