Sorry folks my Internet was down. Anyway I was not criticizing hapkido as a whole but a certain section of its techniques. Some folks need to read before taking instant offense.
Not sure where in the quote you mentioned, or any of the other quotes anyone suggested you were criticizing more then a few techniques..can you quote it, sow e know what you're referring to?
I quoted this above section because it has definite relevance to what I was saying with regard to certain hapkido techniques versus other techniques in hapkido and in jujitsu/wrestling/sambo/judo. Folks may have anecdotes about the techniques and their effectiveness but that does not validate them.
As was already stated, MMA isn't a 'proving ground' for everything, since it has a very distinct format with its own rule set, so not the best way to test if certain techniques are practical or not, as they may be illegal or simply unsportsmanlike in that rule set, and mindset.
If we want to work from a scientific approach we can use the various MMA orgs as a large sample. What we see is very few fine joint manipulations as found in hapkido and aikido as derived from daito ryu because the opponent is fully resistant. Those techniques have their place but it is generally situational and against semi-resistant opponents.
As stated above, and by others, MMA has a very specific ruleset and mindset. As for them being situational, all techniques are situational, which is why there are so many techniques out there. I'm not a huge fan of the phrase 'just another tool in your toolbox', but thats what a lot of these moves are, tools that you use in certain situations.
Now compare with another sample group, law enforcement officers. What we see from LEO's in the case of techniques taught and techniques used is that techniques taught and used tend to be the higher percentage ones which are applicable across more situations. Hence in the grappling department you tend to see takedowns which go after the legs similar to wrestling. In terms of joint control you tend to see jujitsu style techniques where the subject is pinned to the ground, wall, or car to maximize control. These techniques also exist in daito ryu and their derivatives. What you will not see often if ever in these situations is officers using standing joint locks as takedowns or controls with the exception of come-alongs which are high percentage and similar in many respects to high-percentage standing locks from judo and bjj. These are generally employed, again, when e subject is semi-resistant.
Do you have any proof of this? I wouldn't know either way, but some people on here have suggested almost the opposite as far as what LEO's learn, so I would like to see proof. This goes for people suggesting the other way as well, if neither side brings proof, then not really sure the discussion can go any further.
Againto be clear:
- I am not ripping on hapkido as a whole but a certain set and style of techniques within the curriculum and in certain other arts
- These techniques have their place but they are not as high percentage in terms of effectiveness or situational viability as other techniques which fill similar or the same roles most of the time
Thanks, for making the points clear

For the first point, some of the reactions might be because they consider those techniques as a valuable part of hapkido, so insulting the techniques could be taken as insulting hapkido itself. For the second point, I agree with the situational viability, but not necessarily the effectiveness point, if used in the right situation, which once again goes back to the "tools in the toolbox" idea.
Finally, since I think you missed my other post, do you have any actual experience either learning hapkido, or constantly fighting/sparring/discussing with hapkidoists?
