I have asked a lot of people about this and why it exists and I get mostly vague sort of answers revolving around social-ability and hardware requirements from the old days.
I am sure that 2 boxing does help with some small things and there are certain things that it fixes but I think on balance it really is kind of a horrible rule that makes game-play on the server much worse, especially for buffing. Most people don't like boxing as it is, everyone is not going to immediately start running a full group of characters around. But even if they do? Who cares? This is going to make it a whole lot easier to buff, to fill out groups, to actually go places and fight monsters and do things. some people can play 1 guy and some people can play 3, content will still be the same built around the idea of things being a lot harder if you are boxing. I don't see how this is going to hurt, and if it does, it certainly helps a lot more in balance.
