Seriously, I challenge every single idiot that says that cav is easymode to a duel, right now, on the duel server, both mounted. Let's see how easy it is.
And yes, I've seen players like Tommy and Oberyn top the boards with their loomed Sarranid Horses and Lances. But where does the problem lie? Not in the class as a whole, but in the way that the Sarranid Horse gives you manouverability. Plus the fact that they mostly prey on the weak to get their kills. If you ask them, they will reply to you that riding is a semi-useless skill compared to powerstrike, an opinion which I share. A good cavalryman won't go for anything lower than 6 ps, and that's a fact, 7 riding gives you nothing, yet 7 powerstrike gives you that little edge that you might need to finish off your opponent.
People seem to be forgetting that cav received the same heirloom nerfs, same slot nerfs, same drop ons sheath nerfs, a heavy lance nerf, shield skill increase, etc.
