The reason I'd love to see that being changed is to make bunching up for a group activation be vulnerable for CC and not just blasts of melee attacks. Do you risk it or do you split up? Also it'd promote doing something other than always coup-de-grace after winning combat.It’s not just greater than 3”, it’s usually going to be greater than 4”.
At that stage I would be saying it’s just time to suck up that they can’t get into close combat with the other fighter and that they have outmanoeuvred you.
I do feel that a 3” consolidation is probably too far to allow though. I get why you have done it, but just don’t really agree. Maybe it would be better off being half of your Movement value instead of a flat 3” to reward fast moving fighters.
