Big thing? What's the difference from now? MC's already have most of that stuff.but I have one big thing left:
- monstrous creatures: 2D6 versus vehicles, ignore armour, move as infantry unless stated otherwise, are ignored for Abandon as ICs, IGNORE TERRAIN WHEN CHARGING
MC's already have move through cover, so they roll 3d6 for charging through terrain - pretty likely to bring up a 5 or 6.
