As I see it, this patch is not playable for the ancients, and takes the fun out of playing the classicals, simply because:
1. Barbs are rampant and too strong, and once anybody builds the great wall (e.g. blizzrd in Japan), everybody else is doomed to die or be seriously hurt.
(I can see Attila later on, but WTH barb horse archers and camel archers so early in the Middle East?!)
2. Research rate is terribly slow and with no tech brokering, the later you spawn, the better it is, because you can trade YOUR techs for free. Babylon and India were hard already in the last patch, now it's completely impossible.
3. The fault with emperor has not changed: it's still completely impossible with certain civs (almost all the ancients and classicals), instead of really testing the player's skill it's just become an exercise in futility.
4. The lack of squatting "exploits" makes the world more deterministic. No fun at all. I can see why the people who played that Mayan/Japanese SG were so disgusted with RFC after all.
5. More turns for the classicals doesn't mean more opportunity for completing their UHV, in fact, with the slower tech rate, it means that there's absolutely no time for wonders if you want your UHV.
I say return the tech rate to the previous rate (at least until 1AD), undo the early barb spawns, lessen the cost of research in emperor, and let people squat. Squatters rule!
