It is interesting that charge distance in WoTR should come up. In the section on charges it says that the maximum distance a unit can charge is 'X+1d6' and that no charge attempt can be made beyond the distance of 'X+6'. Yet later on the rules imply that you can add Might to extend that distance.

If you read the second paragraph on page 43, it does tell you that other factors (ie Might) could increase that maximum distance.

I thought when it said special abilities can increase max charge distance it meant something like Ugluk's Furious Charge, or the Clansmen of Lamedon Furious Charge, or Wings of Terror.
