Well, one point I can easily concede is that until Larian won't rework their insufferably bad control system, managing a party of six (or anything more than a single character, in general) will always be way more inconvenient that it has any need to be.

The recent addition of the "Group/ungroup all" keybind was a significant (if only marginal) improvement and a better formation control would help even more, but we are still talking of something that is absolutely sub-optimal for no actual reason or benefit.
