You missed the point.
We don't want another civ4. But we want the countless amount of strategies and options availables in Civ4.
In Civ5 you have a single strategy that is always optimal: War rush.
in one game i was warmongering and almost every other AI warned me that this is bad, after i conquered two Civs and annexed their cities i was like starting to dominate but suddenly and just in a few turns almost everyone declared war on me
they smashed me, it's not war all the time, also you can't just invade everyone else there is happiness you know
In Civ5, Tile improvment choice is a no issue. Just mine/Trade post everything
in civ 4 it was almost the same .. mine cottage everything
i do use all sorts of improvements on my lands it depends on what i want .. also there is a good mod that slightly powers other improvements which really makes you consider using them
In Civ5, City placement is non issue. Just grab as much lux as possible.
sometimes you need to settle near a chock point (security reasons) or near a mountain or on a flat land or a hill (to be able to build some buildings) and other stuff + in Civ 4 it's the same you settle near good stuff, that also applies to real world, people settle in good spots no one will found a city in the middle of nowhere
In Civ5, Economy is dumbed down. Food from maritimes, money from Lux trading, hammer from tile improvments
(dumbed) what do you mean, please can you explain to me what was so (complicated) in Civ 4 economy that it is now (dumped down) and city states sometimes are allied with other civs, i once paid almost 2500 golds to win a city state as an ally from the Greeks for strategic reasons
In Civ5, Politics is no issue. Don't settle close to your neighbours at begininig so they don't DOW you. Later on, nothing matters.
i do agree here, but that is better i think it's like they want to win at any cost and any common benefits between you and them is temporary, in civ 4 it's like if you give him a free unit and 15 gold and you share the same religion he loves you all the way to the end 
i love how they think about their own good, i had a war with someone north of me and i was friendly with the civ south of me, i deployed all my units north but then noticed that he started ending all the packs between me and him also some of his military units moved closer to me, so i retreated some of my units to defend, he DW on me cos he thought i'm weak fighting the best civ on the map and he might be able to grab a piece of me, luckily i had a policy which increases the strength when i fight inside my boarders so i was able to defeat his attacking force and move south to threaten his cities (with me at the same time fighting a war north with a very advanced civ) he was freaked out and agreed to make peace for a huge price, i used the advantages gained from him to hold on in my second war
it was such an epic game i had never experienced such a thing in civ 4 
but they should add vessel states back that will make it more fun
In Civ5, money is no issue. Luxuries for 300G and city sale for 1K+?? whats the point of coined tiles?!?
even when selling cities i consider who is buying them
.. like i occupy a city and sell it for a 90 turn of some lux or some gold, or even free just to make someone stronger cos he hates someone else and so they can have an everlasting war that holds them both back while i advance, i even give out military units to balance the power, i judge depending on the situation of the AI's
