If it launches out of EA without some form of native support for a party of 6, it will be really hard not to feel that our EA feedback was basically ignored.
This. We need native support and not a mod.
It's clear they are going for a "easy to mod" option right now but that isn't sufficient. You can get a party of 6 by changing just one variable and it works pretty well except that items inventory screen is too small to be seen clearly (on my monitor at least) and 6 emphasizes the flaws with party management -- flaws that need to be corrected anyway.
