I don't believe anyone is going to read that completely and attentively.
Except the ones that don't really need to be convinced. That's the problem with objective and sensible arguments.
The whole thing is biaised because it doesn't show the advantages of cav, which Renegat pretty much summarized. But still, the points being made stand.
The problem is infs are kids who play for fun rather than victory, and then complain here about th other classes. We'll kill each other so long as you infs play smart and hold, untill the cavs are down.
That's rubbish. Nobody will play a game just for the victory. Victory is only a medium through which you can enjoy the game, not the real end. cRPG was more entertaining to play back when victory mattered less and the overall atmosphere was centered around fun rather than competitiveness.
Also, with less competitiveness the need for balance falls down because nobody cares.
Anyway, I predict that even with no changes cavalry will be harder and harder to play in the future. Infantry already plays in loose formations, usually with pikes on both flanks, which prevents cav from attacking the group where it is weak, and with ranged support behind, which will do just as good, in a much wider zone.
In a group of infantry or ranged players, one aware guy is enough to cancel the horseman's attack and damaging/killing him and his horse.
Cav tends to be much more risky than infantry because safe kills are very rare. If you hang around the enemy group, you are alone, you will get shot and enemy cav will attack you. If you are downed nobody will come and rescue you. Infantry and ranged players on the contrary can very safely move and attack together, providing direct support to their allies.
Cav groups can do teamwork too, but cav teammates are much more dangerous than inf or ranged, even for other cav, because without precise coordination they will block your path and make you a sitting duck. There is nothing of the like in ranged or infantry groups, where only basic/no communication is required to make full use of your teammates.
As much as dealing with groups of enemies aware of you with any other class gives you decent chances, providing the group isn't ranged, is it borderline impossible for cav. Defeating one guy aware of you no matter his class if he doesn't take risks to kill you already is very difficult and relies more on his errors than on anything you can do (lance thrusts are the easiest weapon to block and chamberblock in the game, and dodging couched lances is only a tad harder, all with heavy armor of course). But if you ride close to multiple enemies there's bound to be one that will hurt you or your horse.
It takes something like this :
