So the maximum number of players your party can have is 5, to be expected, that's the way it usually is after all.
...But with GW2's difficulty-scaling, is it really necessary to limit players like this? I know it's going to be a bit difficult for me, at least, to play with 6-7 other people at once.
Is there some other reason that they decided to go with 5, or is it simply for tradition's sake?
