England as it is, is a weird construction. Look for example at Germany, Babylon, Zulu or Denmark. All their UA and UB, even some UU are going hand in hand to maximize in the end the benefits of all the abilities.
But what is doing England? You have one more spy (I was really surprised I only got one more spy, cause the description gave me the impression, her UA would give me more spies in addition to the regular one in renaissance), a cheaper fleet with a really strong UU and a good industrial UB. But nothing special. No synergies.
I would expect something more from a nation which was once the most powerful nation over a long period of time. (Yeah, other nations may be as much powerful in their period of time for a longer time, but not that global like GB was)
Historically, giving England the abilities of Venice or Mongolia would make much more sense to me than giving them to their originals. Assimilating smaller regional powers by military pressure or diplomacy, even with a lot of financial power was one of the keystones of Englands success. But I didnt see that represented in their gameplay.
I could imagine they get more spies, like every 2 eras, beginning with classic to improve their espionage part, stay with lvl 2 spies but remove the naval benefits. CS with infiltrated spies are 25% easier to bully and ships are 25% better at bullying CS.
For a greater synergy, steam mills generate yields, every time you get tribute/heavy tribute from a city state.
OR
CS with strategic ressource gift one permanent copy of their strategic ressource to england, if a heavy tribute was forced.
In my eys, such combination would represent englands strenght much more then the present one.
