There is no such thing as fair fights when it comes to survival. If you find yourself in a fair fight, you are either in a competition, or your strategies sucked.
In my opinion, survival or a trip to the hospital depends on these factors, in this order:
1. Mindset
2. Opportunity
3. Environment
4. Attribute
5. Techniques
While it is entertaining to argue over what techniques works when or where, and testing it against friends; it is really the least important bit. Yet we tend to over emphasize on techniques, and forgot to pay attention to the other factors.
Since most of us on this forum are honest law abiding citizens, we tend to visualise a fight to be open and fair. Because that's how we normally conduct our affairs. However, the person smashing a glass bottle across your face may not have such honorable courtesy.
You have to honestly ask yourself, is your WC techniques alone ever be good enough to deal with someone twice your size? with weapons? with multiple attackers? jumping out from behind in a poorly lit carpark with a screwdriver in his hand?
I guess, it really doesn't matter what you are training for; as long as one is honest to himself and not delusional about what it is about.
