Yes, it's a complete mess. Managing the party in itself is a frustrating mini-game.
If the the "party" UI and functions will remain unchanged, then we need at least a keyboard map to unlink all and another to party them up again. Also each character needs a hardcoded F1 to F4 link, so F1 always selects the same character and they never switch places. Clicking with mouse doesn't select them, like needs clicked 2 or 3 times until reacts.
This stuff should have been seen during early Alpha; it's very bad coding and party management "solution" for a game that constantly needs to select each character, one by one, all the time.
