Yea, Ignore England. You get shit up if you follow them.(depends on you, try to wait out the years of the hundred years wars. England WILL lose, just depends on time.
Or, you can do other things, like NOT war morrocco(actually a good idea, btw. Converting to catholic will be hard that early). Spain will go for you, so getting powerful allies to counter Castille is smart.
As an FYI: with England, I hot joined, so the AI was some 700 dollars in loans(12 74 dollar loans) involved in 2 wars(burgundy and France) had rebellions out the wazoo, and...well it suck bad.
50 years later, I paid back all debts, owned Scotland and Ireland, and had the biggest navy. England is a good ally, just they start off real real bad. gotta wait it out by like 30 years.
