Okay, but ganging up on a solo hero is the kind of tactic that is inherently unfair but expected of bad guys. Try not to get into that situation and learn to retreat if you get the chance.
We've gone over this (and over this) but one or two Heroes just chaining a Knockback effect could easily keep a an adversary, regardless of AL, effectively unable to do anything for an entire fight. The Knockback effect you are a proponent of is irresistible: it's effectiveness is based solely on the dice roll of the attacker. Which means it's equally effective against a Snaga Tracker as it is against The Witch King. So you may as well never have solo Adversaries, no matter how powerful. If that's not game-breaking OP I don't know what is.
There are very few attacks associated with Knockdown (only one so far officially?*) And maybe that is for the best as it can be pretty devastating. Most heavy weapons instead have Break shield if they have a called shot at all. However, a called shot is not guaranteed to succeed every time it is attempted. And you point out yourself that a hero who is knocked down is likely to have teammates coming to his aid. I have to wonder if your objection would still be as strong if there was a weapon in RAW that allowed a hero to achieve the same effect.
Now, if you are knocked down as part of a one-on-one mounted contest then you are probably going to be able to recover your footing before a mounted opponent can return for another attack. And, depending on the rules of the contest, your adversary may himself have to dismount in order to continue the fight, allowing you even more time to recover.
* I had forgotten about the Children of Shelob--Sarqin, Tauler and Tyulqin--who also have Knockdown as a called shot.
