I actually explained it
No, you didn't. You said you would feel more forced to make this kind of choice if you had more room in your party (which is a dubious and fairly counter-intuitive claim in itself since usually the less room you have, the least you are left free to experiment with classes, but I didn't argue about it).
You never said WHy and in what way that would be bad, given that, as you pointed out yourself, you'd still have two slots to experiment with "whatever you like" (which reason suggests you wouldn't, with stricter party restrictions).
By the way yes, I'm opinionated about these things.
For some of you this may be just about making a poorly argued throw-away comment "I prefer four because six super slow", based on guts feeling more than facts, about a game you will mildly care about for two weeks and then throw to the pile of old stuff.
For someone like me the genre is a lifelong passion, and good titles in it are stuff I plan to go back even dozen times, if the depth is there.
