The idea behind neutrals is good, unaligned players doing their own thing. What will really happen is people will abuse the neutrality to circumvent restrictions on the nationals. Especially if you can have more than one character.
The whole "people will buy new accounts anyway so let them have more characters" argument is a load of rubbish. Don't make it easier for them if it's going to be a problem. One character, and if people really want more they can buy them. Like people keep saying, they're going to do it anyway.
