Nub, I didn't say they were directly better.
The hussar class can do things the heavies can't, and vice versa. I was protesting the notion that they're worse than hussars and that they're less useful - and also claiming that hussars are far easier to play.
Largely, hussar relies on having others make mistakes for them and dipping in and out as you please, and never being caught by others. A hussar regiment can just run away or dart in quickly, whereas heavies have to dedicate a charge; this requires more thought from the commander, more skill from the players (you can't run away, you can't outrun the enemy cavalry, you can't run into a bayonet, ever, but survive stabs) and a good amount of teamwork. A heavy regiment has to be closely tied, as someone has to be the linebreaker and the one who grants the others the kills, whereas light cavalry can gallop around and snag their own whenever an opportunity arises.
Thus, in my opinion and experience, hussars are -far- easier to play, easier to get kills with, but not necessarily better than heavy cavalry. One is a constant needle in the eye for artillery and skirms, the other smashes through formations like nobody's business and can easily carry a team to victory with a good charge.
Note that I'm not claiming that hussars aren't hard to master. There are pretty damn good light players out there, and far more of them than there are heavies.
so tired why did i write this i will regret it in the morning
