Have you ever played a video game before and not run into an OP unit or character? Even the most balanced games have OP things within them, this is a ridiculous attempt at argumentation.
The fact that cav can and often does carry does not change the fact that it is a support unit whose job is to counter opposing cavalry and help your infantry win fights. It does everything archer does in a more efficient way because you have a mobility and reach advantage. Yes you can often garner many kills doing this but that doesn't change the fundamental role of the unit which is always to support the main fights when even or up. In casual modes like captain tdm and siege it functions the same way though in siege and tdm killing opposing cav is less important because the battlefield is far less contained and fights are all over, though it is exceptionally easy to kill most cav playing those latter two modes.
Do you know how incredibly easy it is to kill the people who take light cav and spam x? 90% of them have no concept of how to move, turn, block, thrust, or stab correctly and because they are casual game modes it takes almost 0 effort yourself to get light cavalry and counter it. Yes the game isn't rock-paper-scissors you're not always going to win as inf with a spear because the hitbox isn't consistent enough on either horse rear nor rider's head. Doesn't mean you can't still one shot cav with a pike that isn't even braced or brace 8 ft away in the wrong direction and get a miraculous one shot because of said inconsistent hitboxes. If you don't find non-competitive casual gamemodes fun either stick to comp skirmish with class limits, play single player or play something else. How difficult to understand is that?
Yeah plenty, in games where balance is done carefully and with reason, instead of "cavalry was strong irl therefore must be overpowered in a video game!!"
Every game have aspects of broken things, which is why the developers should work on fixing that. They dont just go oh screw it, lets just let this thing be the walking apocalypse and hope people dont mind.
I dont even know how to start on the second paragraph there. Cavalry is not support. Infantry ties down units to make cavalry get easier hits, because cavalry have a way higher damage output. Look at the statistics for BEAST and you'll see how great supporters cavalry are, so great in fact theyre the top killers of almost every division by far.
And here you're making my argument for me and seem you dont understand why. If the only counter to a class, is to play the same class, then its obviously not balanced. In your world, everyone is a cavalry player, and thats apparently fine for you. But not everyone wants to play cavalry, and not everyone should play cavalry because that will destroy the game. This isnt Destruction Derby. Stop making excuses for how blatently broken cavalry is.
The "if you dont like it, just leave" yeah thats the problem isnt it. 90% of the playerbase didnt like the game, so they left. And now we're stuck here with barerly anyone playing.
I do just fine in non competitive gamemodes because I have years of experience playing these games, a new player however will go into TDM or siege, hear the clappidiclaps of death and just die to a player who just brainlessly click X and hits them for 200 damage.
