My gaming group really like LR (and derivatives) but we have had a few games recently where crossbows have rather dominated. We played one last night using the Garrison and Rebel forces suggested in the rule book and the two units of Garrison Crossbows just trashed the Rebels who were really unable to deal with them. In real life of course, such rebel forces did lack firepower, but even so. It's not the first game we've had where one side has struggled against a wall of Crossbows.
I think the problem is that, although Crossbows require a higher shoot activation than Archers which is supposed to represent their slower rate of fire, with everyone now having the command ability which allows one re-roll of a failed activation both units activated just about every time. With them hitting on 4+ within 12" they can really do some damage especially against lighter armoured troops and it seems disproportionate.
I would be interested to hear peoples thoughts/experiences. At the moment we are considering upping their Shoot activation roll to 8+ instead of 7+. This would put them on a par with Artillery in Pikeman's Lament. I'm not keen to reduce the fire factor, which would just make them the same as Archers.
