Well, the Lithunians certainly arent:P
Ask my Lithunain infanrty commander who is currently on garrison duty in Egypt, at 1160:p
The Lith infantry is simply amazing...

I would say Volgo Bulgarians in high, bascailly you got some ok Cav and the horde will be on your toes in 15 years.
I would say that Scotland is a bit easier than Armeina, storming engalnd is not that difficult, you got some ins for a reason.
In addtion, the English King start in France, so you will have free riegn for a while.
Armenia hmm...
I did not play with them, but their positon is certainly not favoruable.
