So there is this awesome little thing we use called Combat Drugs. Wyches got 'em, Reavers got 'em, Hellions got 'em, and any major character in the army has them. So on those traveling by foot, how do you do sweeping advances when you have a 3d6 pursuit. In 3rd ed you'd win combat and roll to see if you catch up. But now you roll the I test, see if you catch them then if you do it's a massacre result, or it's a consolidation, not this 3d6 pursuit thing. How does it work for 4th edition? Is it just ignored and only applies to FB moves?
