Your direct, pointed feedback has always been helpful.
Thanks. It will be a while before I can give much in the way of sensible feedback though, so much has changed that I need to get a good feel for how things are working first.
Still, the overall play is very fun.
From a bit of play:
a) I really like the defensive bonus for spearmen. That was a great design decision. It gives them a role and makes them useful, but retains their overall inferiority to swords and horses. My only worry is that it makes them a bit too good at defending against ranged attacks - which dense formations should be vulnerable too - but maybe that is ok.
b) The first game I played, somehow the English managed to beeline to Fighters very early, and their large stacks of fighters absolutely annihilated my ground-based army, through focus fire.
Not quite sure how they got there so fast or were able to field so many. They could wipe out one of my units every turn.
c) It seems now that balancing wars are very important. The incentives are quite strong to pick not on the weak guy (because the gains from conquest are now pretty low) but on the strong guy. The main goal of most wars are to weaken the other players, not necessarily to conquer them, and so to try to cement your position as the main late-game superpower.
d) With the latest beta, I seem to be observing some nasty UI issues. Mostly its fine, but sometimes if I load a game the UI doesn't load, and I have to exit Civ5 to get it to work again.
e) I am very often getting horses near my start, but never iron yet.
