Aren't those ranged weapons ? Variety of tactics ? Like equipping invisible pike/light lance, longest 2h weapons can stab the horse and kill it in one shot (? with old animations they had the chance, i dunno if it's possible with new) - if they fail to kill they are dead.
I know that ranged can counter couch, thats why i said 1h/2h are dead/shieldless.
I see where you are coming from.
I will concede that 1h weapons are at a distinct disadvantage, but 2h weapons in crpg have plenty of length. Often they can safely attack the cavalry's left side. On top of that, using the map's terrain, a clever infantry will still have plenty available options.
On flat plains, with no cover, cavalry will have an advantage, but it is the responsibily of server owners to evaluate maps for rotation and ensure they are balanced.
There are still plenty of ways to counter a couching cavalry. I still don't feel that couch is easy-mode or in any way overpowered against a knowledgable opponent
