No, I was objecting to the fact that you were trying to bolster your point by referencing examples that didn't support it. You don't get to say FFXIV ought to have a 4-person party configuration, and then cite games that don't have that as evidence.
FFXIV dungeon parties are made of 4 players, not "3-4" or some undefined "fewer than 5." It's 4. If this game had parties of 3 members, it would be a very different conversation (if such an MMO could even function, that is)....rather than the fact that the Home Audience for FFXIV was Japanese, used to Final Fantasy games (which are JRPGs), which have traditionally had fewer than 5 party members for encounters.
Do you honestly think anybody would be upset, or feel that it's "not a real JRPG" if FFXIV had come out with 5-person dungeon groups? How about Final Fantasy IV? Is that not a real Final Fantasy game, to you? Is a single-person increase in the size of a party really what defines what a JRPG is? And why do big story arcs cap off with a "full party" of 8-person groups? Don't they care about that "JRPG feel" anymore?The fact that you, personally, wouldn't have been outraged if the game lost some of that traditional "JRPG feel" doesn't impress me.
Dude, YOU are the only one appealing to tradition here. Your entire argument is nothing but explaining that it was a certain way in the past, therefore that's how it should be. Just TWO SENTENCES AGO you literally said: "Final Fantasy games (which are JRPGs), which have traditionally had fewer than 5 party members for encounters."Nor does it provide an answer for the question "what's the particular advantage of the 5 member dungeon party?" other than because ... tradition?
Anyway, as far as what the advantage would be of 5-person groups in an MMO, you need look no further than what this very thread is essentially about. People need to get into dungeons. Most people play DPS, and so the queue time for DPS is disproportionately longer than other roles. They literally had to install a system of rewards and incentives to get tanks/healers to run content repeatedly, just so people can get into required duties. If you had 3 DPS per group instead of 2, that would certainly help alleviate this problem somewhat. That's why I mentioned that so many other MMORPGs have 5-player groups -- because even in those cases, DPS still have longer queues. It wasn't because it's an MMO "tradition" or that the number 5 has some magical "feeling" about it.
