Yup. And if that's all you're interested in, well, adding another method to get 'best' gear would ultimately just result in "well now I'm done everything NOW WHAT SE" even faster.
This isn't to say the game couldn't benefit from more content; especially content with spontaneity/nonlinear generation that would greatly increase the amount of people's interest in replaying it. But there would always be a set of players only interested in "does it have the best gear in the game at the end of it".
