Just casual chat...don't really want to suggest this idea
As you experienced FF14 players might already know (/chuckle), some monsters have the habit to change their position during fight and some did WS accordingly, such as deer, monkey, wolf... So the fighting position AI for mobs is there.
How about making them do the position combo too?
I'm sort of glad/scared to ask that because I want to see friend got serious WS combo damage and die, but not on me :O
