The ring isn't a "real fight"...
To fight for the ring isn't "real training"
The supreme martial art to win over all other martial arts is this:
If you fight for the ring, then sure, train for fighting in the ring, but dont ever confuse it with the ability to properly defend yourself out in the street.
Its true that by fighting in the ring, you gain some pretty useful abilities that could come in handy in real life situations. Like learning on how to predict a opponents body movement and take a punch amongst several.
But for every advantage you gain, there comes drawbacks. In real life situations you wont have the luxury of being able to study tapes of previous fights by your opponent to learn how to predict his tactics.
In the ring, your opponent wont have friends to come to his aid. In the ring, your opponent wont suddenly slip on some knuckle dusters, pull a blade or swing a bottle to your head.
Tons of things can happen, and all of a sudden all fighting in the ring has done is given you a false sense of security.
Morihei Ueshiba himself didn't approve of competing in Aikido.
He didn't create Aikido to teach us how to "beat people up"
He didn't even create Aikido to teach us self defence-
He created Aikido to promote peace by teaching methods on how to enforce it.
But not force peace by "breaking someone's arm so they calm down"
or even "I WILL break your arm if you don't calm down" but "I CAN break your arm if you don't calm down"
In closing, if anyone wants to learn to fight in the ring.. go train Boxing, Judo, MMA, Shodokan or BJJ or whatever. DON'T go train (regular) Aikido and expect it to adapt into a Sports variant just because you want to "try its effectiveness".
That's my view of Aikido anyway, it may be in conflict with yours, but its how I perceive it and the reasons why I train it.
And I train Iwama style Aikido and it's not known as "Lumberjack Aikido" for nothing.. we can get pretty rough at it sometimes.
But we start carefully in the beginners level and then gradually increase resisting and countering techniques.
"if it don't hurt, it's not working" as we say.
