If you're playing with a lot of water, then England are really strong, otherwise I'm not personally convinced that Longbowmen are all that great. By the time that tech comes round, my ranged units have 'range' anyway, and there isn't any difference I've been able to discern between having 3 and 4 range, since both are more than other units/cities.
I'll take China/Arabia, etc. over England any day.
If I was to play as England, I'd probably explore what can be done with the extra spy in combo with Oxford and other 'boosts' to see if I can hit Autocracy super early and start my way towards Clausewitzian insanity.
don't think you can get range 4 on longbow (that would be truly ridiculous; attacking from another continent kind of ridiculous )
Keep in mind range allows them to attack a hostile city every turn without retaliation (units should not be a problem against a pack of xbows especially longbows ) .. Attacking cities grants 50% more XP than attacking units ... Keep a weak city/CS near your production cities to quickly train the new recruits ... So you can "quickly" train your longbow army to get (both range they start with it/get it at upgrade) and logistics ...
7-10 Xbows ~T130 with range and logistics won't roll deity maps like keshik//camels but are the next best thing ...That deals with land .. And on water ...
