Tis true though. 1h cav will bump you to death because they can afford to turn in a tighter circle. But I've seen plenty of people survive against 3-4 lancers just by skipping sideways+downblock+ making them get in each others way. It's not that complicated. Cavalry in groups are pretty notorious for getting in each others way. All of them kill hungry...all going for the kill at the same time means a bad end for them.
There are plenty of good infantry players who can survive against 3-4 infantry, they might not kill them all...but they can survive long enough till help arrives. So no...it's not a ridiculous argument. It's more a matter of knowing how to play.
It is a ridiculous argument because you are saying its not that complicated. Once they bump you, and if you face 3-4 cav they WILL bump you, you are as good as dead. Kinda hard to downblock/sidestep when your face is eating dirt. You can downblock/sidestep all you want but its just a matter of time till your face hits the ground. Bjord is toast, Xant/Siem is toast, Chase is toast, Cooties is toast i would go as far as to say that Crafty would be pretty badly fried toast.
Not counting the cav that is completely incompetent. Meaning in your case: They bump into eachother like retards, kill themselves etc. Thats just people being retarded
And this is perfectly fine, working as intended. If you are stupid enough to go on a open field vs 3-4 cav you deserve to die.
Which leads us to the core problem here: battle awearness.
People getting in these situations and then QQ-ing: omg cav is op. Its like facing a roof with 5 crosbowmen and instead of hiding you dance in front of them spamming: [.S]hoot!
