That's not the issue, this is:
"It seems to trod on the very reason it was introduced and used. :S".
The Dempsey was supposed to be hard to hit, now they're telling us it's actually easy to counter. If we wanted to be realistic, then the earlier form of calling it incomplete because it needed to be executed at a distance was perfect. You can't hit Ippo, but you can stop him by leaning on him.
Giving it a weakness like that is good, but to fundamentally break it makes you wonder why it was even introduced.
The mexican world champion being able to hit Ippo during their spar was supposed to almost humanly impossible.
