We-ell, as stefan said it probably won't make a difference to most people, but it will make a difference to a few. I think this because there were some people who
did use the party system, and especially lower level people love the idea of working together (i know i did). But now, you have to be in a guild or a kingdom to work as a team and this might not be possible for every person.
I'm not sure how it will turn out, i think the change is quite nice (it encourages people to work with their associates rather than just their buddies) but it could have some stings in its tail
