^ Yeah, was disappointing that the cover determination rule didn't change.
All that is really needed is to change:
look at it from behind the heads of the firing unit’s models.
to
Determine line of sight to the enemy unit from the firing unit's leader as per the standard LoS rules
They have a great quick system in place for just using the leader for everything to simplify matters. This idea needs to be extended, quite possibly ditching the separate BFGs rules for the sake of streamlining... even 40k doesn't indulge in that much individualism. "Leader for everything" would be so much easier.
