See, this is the kind of attitude I think is hilarious. It's just flat out not true, and most likely a way of personally justifying registering for masters, which you shouldn't have to do.
First of all, number of competitors. In most cases the adult division has at least double the amount of competitors, having to win multiple matches just to podium. Most competitors are in the 18-25 range, filled with testosterone and no family obligations. They are in shape, energized, and train like crazy. Even in masters 1, it's a good bet that everyone has a full-time job, injuries, kids, etc. It's really night and day.
I think what you're trying to get at is there are tough people in the masters division. Someone earlier referenced Xande and Lovato Jr. being at masters worlds. OK then, take a look at adult worlds and let me know if you still think masters is as tough. Masters is tough relative to your skill level and commitment to the sport, that's why it exists, but it's not even close to as competitive as the adult division.
