Wait what?? Imladris shouldn't be a cavalry faction. I'm not saying Imladris shouldn't have good cavalry, but it shoulnd't be its focus either. Sorry for going off-topic
I understand the balance reasons but revenge damage still looks very silly. I mean, wouldn't there be a way in which to make some units in the batallion react a certain way and others to react differently? Some would be able to stand their ground and others would would get trample. This mixed option, if possible, would be even more realistic I guess, given that not all soldiers would be able to resist, but most would, instead of all of them getting trampled, which simply doesn't make sense. After all pikemen are the cavalry counter.
