There won't be more hours. Just a higher hour cap. So what's been suggested will simply play havoc with the pacing of BM. Having armies wait around to stack up hours before every engagement doesn't sound any fun to me. Of course, you could always increase the number of hours per turn along with the cap, but then you still have the same relative problem. I feel like we're trying to fix something that isn't broken here.
The hours don't pop out of nowhere, that is true. These 4 extra hours of looting (or other stuff) will be taken from the period before you enter the enemies' lands, meaning that the intervals between attacks will be about one turn longer than before. In other words, the predicted effect of such a change would be that armies would fight slightly less due to a refit time increased by 1 turn but that every strike would deal slightly to moderately more damage due to everyone having 4 more hours worth of actions every attack. This is because armies usually cannot remain to loot for a very long period of time, as after they win battles they are damaged and the enemies' refitted troops could likely defeat them in the next battle if they remain, so those are 4 hours worth of actions that could otherwise not have been taken.
