Yes, I agree to all that was said before... even if you managed to unchain your party members, you have a chance to accidently give silly orders while picking one ore the other. Had the case e.g., that I made my group jump one after the other over a fire and three were done already. While trying to pick the remaining member, the 3rd in row turn round to walk back and die... Or you jump with the leading character and the others pick a detour instead of a jump and run into the next group or trap.

Anyway... just try once to position three characters in favourable positions before kicking of the fight with the last remaining member. There is a more than big chance that you either mess up the positioning because of the complicated handling or that you realize that you're to far of to join the fight in reasonable time in the end.
