So we have a tourney going at a local shop and we have a group of guys who have been playing that when a unit that is already engaged gets charged by another unit they cant attack that unit due to the first bullet point in the multiple combat section. After showing them the errata and and how the wording was changed they still dont understand and feel like they are being cheated since the are not local to the tourney. Does anybody have a clear cut way we can describe this while keeping the peace?
