I've seen some walkthroughs/faqs/character-creation guides and some claim that the front character gets hit the most (I suppose "front character" means the left-most?). But in my experience, I can hardly say that's true. Also, official manual doesn't mention it. In MM7, it also seems that the party member order matters for bowmen - as the arrow flies from the left, middle or right, depending on the position. But that's about all I noticed.
So, could you please tell me more about the order of party members, particularly in MM6, MM7 and MM8?
MM8: How, for @#$@#%'s sake, do you change the character party order?
In this thread, people said that party order has no effect in MM6, MM7 and MM8, but many online guides claim otherwise. :-(
Party Order and Switching
Here, people claim it affects XP gaining and geometry of ranged attacts
Might and Magic 7 focused fire issue
Here, they claim that starting in MM6, first and last positions are slightly more targeted by monsters.
