We mock what we don't understand.
I prefer no time limit. When I work hard to get a guy down and I have great position I like to milk it, make the other person suffer, carry my weight... I fight in venues with 5 minute rounds. Broken up in three rounds. Sucks to end a round in great position.... this is what we got.
There's nothing more beautiful than an uninterrupted fight. There's wonderful drama involved. There is so much subtle battling going on for position in the ground game. If you knew what to look for its just as rewarding as seeing a nice strike. In some ways a great strike requires an element of luck (guard down, run into, etc.) Setting up an escape/reversal is beautiful. It's beautiful to finish.
