Adds yet more randomness with leadership tests just to be value for the points. No thanks.
Just tweak the points costs. Scenario design and terrain rules should keep BS shooting in check, not yet more special rules creep be it orders or whatever. Price the State troop shooters at 6.5 points or whatever. Warhammer could benefit from having victory conditions based on capturing and holding ground as well as just casualties, to encourage more movement and less static forces to offset the BS shooting being effective. Make it worth the points, but make a general want to take other stuff too basically.
