At first I found them useless, but now it’s slowly becoming my favorite class! I’d say it’s pretty balanced with infantry, but obviously a lot worse than tanks or planes.
The most annoying thing is getting stuck, but you kind of learn to avoid the tiniest of branches. Still happens way too much though.
But if you flank, play careful, it’s just so satisfying to stab people in the back and ride away.
I think boosting the horse health by 10-20% would be fair, they do get taken down fast. The rider health seems okay, people seem to go for the big mass of the horse. A single LMG is currently a bit too effective against it.
