This is rather condescending
How many playtesters do you think they have? Dozens, even at most low three digits? And upon release, how many players do they have? Thousands, maybe even 5 digits.
That big a group of people are bound to think of more than the smaller group.
Publish something of your own and see how many people find holes in YOUR product.
Are these digits in reference to their IQ's or are you giving us the fingers ?
