the biggest problem i found with tkd and most traditional styles was the lack of drills. maybe i went to the wrong schools but i never learned anything about how to counter and time when sparring. i mean never. i had to just blindly figure it out. they taught us kicks and combos etc, but never did we drill and stand there and have some one throw a kick and you practice just blocking and countering with timing drills etc. like you see in boxing and kick boxing. i mean never ever did we do that stuff in tkd.
