There are limitations in EVERY martial art.I follow nothing blindly, on the contrary I'm studying pretty hard and my conclusions are based on my experience... There is no limitation in any martial art... The only limiting factor is each individual person's skill... But how can you define skill? Well, you've got Aikido skills, when you are good in Aikido. What's so difficult about it?
Having understood that it saves me the excuses of blaming the art and makes me work harder... Maybe more people should do that...
