+1 from me as well, even though I don't consider myself a bad player, and usually handle myself adequately on the battlefield, it is noticeable that heavies facing hussars is rather one-sided
if both sides have better than average players.
One could always try to beat it via tactics (heavies should stick together, hussars should pick off heavies one by one) etc. But it comes down to the fact that in a non-realistic game, 1 hussar taking out 5+ heavies simply because of his speed and agility, creates far more instability, than having heavy cavalry be stronger in HP and 'reach'. It simply makes sense that heavies are much stronger, as it makes sense for hussars to be more agile. Hussars should beat by numbers, not by evasion and 'skill' of a single member. Thus a nerf/boost would make sense as well.
Thus I concurr with Patrykus' suggestions
Spoiler
My suggestions:
- heavy horses should have pre-patch stats
- French, Austrian and Russian cuirassiers should have better armor value.
- magical hussar's sabre thrust should be much weaker (maybe reduced speed bonus would help).
