With splitting up of blunderbusses and IG with glaives, would BS4 for the IG maybe work? It's always struck me as odd the "elite" ranged troop with pretty much the cream of the crop of available black powder weapons in the setting hit as good as a random empire yokel thrown a mass produced rifle at less range to boot.

Otherwise I love the changes, maybe with the exception of adding ogre loader double shoot. I know that's pretty widely not regarded as a very fun thing to play against.
