I was not aware of those limitations, although I'm not surprised seeing it on an mmo game either. I'm not certain why you aren't able to invite to parties, but the rest seems designed to cut down spam. Anyway, I thought you might have had a friend in the game already because of the recruit-a-friend program. Best of luck out there, and if you're ever on Leviathan (you may have to create the char at an off-hour), feel free to look for my character.
