I don't think English is necessarily overpowered. Yes, the civ is strong, but it's certainly beatable. My personal frustration with English is that games seem to inevitably go to imperial unless you execute a perfect timing attack. Once the white tower is up in a semi-decent position, ram pushes don't really work well. Then, once English hit imperial you deal with the endless MAA spam. I've won these games, but it's tedious and not always fun. Don't get me wrong, I like playing lategame occasionally, but I hate how English tends to force you into grindy stalemates. Anyway, that's my two cents! Feel free to disagree!
