How?
Adding in my suggestion, again on a pop adjusted basis:
Cost in VS 130.953 per pop (same as current)
7 speed (faster).
120 hp (now with 30% RR at base, 40 with the native tech if you get it).
14 hand attack, that’s slightly worse against infantry but 40% better against everything else)
Charged attack is straight up better because it’s the new base attack turned to siege damage +1.5x vs infantry.
By not charging siege goes from 6.667 to 10 on a per pop basis.
The only loss is a +5/5 from cards and a probably necessary nerf to Grand Hetman, but with the buffs this is outweighed. Also you save 1 card slot on your way to FU Winged Hussars. I basically just buffed them and adjusted them to 2 pop.
Edit: btw they will be easier to train on a per unit basis (because affording 5 is less cav overall). Also, I forgot that I added them to Rider of the Apocalypse, so they actually do take the same number of cards to upgrade if you want the +30% siege.
