Frankly, the whole Ranked Server and Account Server thing is crap too. They aren't being very clear on any of this and pi$$ing off a lot of folks. EA's BF2 forum in the UK is full of gripes and complaints.
EA is claiming that if you modify the server code (like unlocking all the weapons), you're violating the EULA and that your an evil hacker!. Um.... what's funny is that on the back of my BF2 manual is an order form a book of official EA CHEAT CODES. Can we all say, dur.
