Get rid of armbars, kneebars, kimuras too then cuz they can cause career ending joint damage. If the fighter is too foolish to tap then they can incur the consequences.
As for the elbow padding it wouldn't work. Even neoprene slips as evident by anyone that wears knee wraps/pads. But the thinness of the pad wouldn't dramatically reduce the force of the strike.
That just sounds straight up ignorant!
from what you are saying it sounds like you do not know the mechanics of a heel hook and why its the most dangerous submission.
First of all, all other joint lock submissions deal with some form of hyperextension. They are very painful and it takes some effort to do some hardcore dammage. You would have to be a complete piece of sh1t to do really seriouse career altering/ending dammage to someone, because the fact that the guy you are doing a joint lock submission on has time to tapp and scream out in pain before you get to the point of completely tearing something out. There is a pretty good range of motion you would have to go through to do something seriouse. Not to mention the fact that you would feel all kinds of cracking and tearing that would signal you to stop. If you are in competition and you feel the guy tap or scream out in pain and you keep cranking then you are a skum bucket piece of sh1t.
That is not the case with the heelhook. The heel hook attacks the ACL.. you do not feel any real pain untill your ACL pops..there is no gradual poping or tearing, the ACL just pops in half and by then its too late to tap, scream, or stop cranking. And the range of motion and effort required to do that particular submission is verry small.
And the ACL is just the first thing to go, once it tears there are a bunch of ther things that can be damaged...
I have heard of too many people and seen it first hand in tournaments and fights where guys crank heel hooks, and hurt their opponent seriously... by seriously i mean surgery is needed, after which you have to learn how to walk again and your leg will probably never be as strong and stable as it used to be.
No one is going to miss heel hooks, no one is going to be like "damn those heel hooks were soo exciting to see.. i wish they bring them back"... taking out keel hooks would only help the sport not hurt it.
If you think otherwise your just ignorant.
