I always thought these complaints were just the tears of an OP class that got it's long deserved balance, making other lances actually viable choices. I also thought that the heavy lance with its slow speed still benefitted enough from speed bonus to do good damage. I have played my cav alt again though, sure 6 ps and an unloomed heavy lance might not be optimal, but glancing on full speed proper hits is a bit ridiculous. I feel like I do more damage to armour swinging my unloomed cut damage LHB on foot with 5 athlethics than stabbing someone at full speed with the pierce heavy lance.
Seriously just whiffing and glancing all over the place, although I am not sure if it is the damage nerf, maybe something about the stabbing mechanics got changed, cause I remember doing better even with a 4 ps unloomed 26p heavy lance when my cav alt was still built for the great lance, which should be about equal.
