Yeah, it's hard to tell what people actually like at times, and even talking about it can only offer so much data. If only there was some situation where we could have a temporary, incomplete state of the game in the hands of its audience and take this peculiar chance to experiment with features and options to see how the user base interacted with it.
We could call it "anticipated introduction" or "premature entrance" or something of that sort.
They should have included an option in character creation to choose between a 4 and 6 party limit (for EA only of course), that would have been great at launch and would have supplied feedback from hundred's of thousands of people which cant be ignored what ever the results would have been, unfortunately that ship has sailed, now you have what 20k people playing?? that might not be enough to change their minds if they believe these 20k dont represent the majority
