Infidel!
What they call random clicking is in fact random setting. Meaning that you are making a form of the opener but not by exact coping of openers that others already made or from the yotube, no. You are actually making your 'opener' live, from your experience and knowledge of how tori-body works.
What Snake calls 'random clicking' has enough randomness in it to look like that, but its actually more of the instinctual process of making new opener.
Mostly, ppl that copy moves and do openers using pre-set moves from the TB wikki or yotube, are lousy come-back makers. They do the opener, fly in some direction and they can't get back into fight, because they are not using their brain to form the knowledge of movement of the tori-body. Instead, they use their brain to memorize openers.
Without come-backs wushu isn't a fight, its a 'how far can I fly' mod.

There are some players that use both. Opener or variation, then improvisation, but those have played enough to apprehend the basic understanding of the tori movement. Since they know how to come back into fight (and that you can't learn copying openers) they are forgiven for using openers!

Basic understanding of the tori movement in wushu is best learned from 'random clicking'.
The fact that you (or some other ppl) DQ too much using it just means that learning curve is too steep in Toribash and you (or some other ppl) doesn't have patience. It takes time, but in the end you get it.
And when you get it, then you will understand how openers are inhibiting the freedom of fight in wushu through random settings.

I would just add that there is also a 'opener mimicking' thing. You study the most used opener and its variations, then you do the opener first turn, then randomly transform it to new setting, and by that surprise opponent.
Most ppl when they see some very popular opener, prepare themselves to defend from it in the second turn, then you surprise them with randomization!
