I agree with much of your post!
I disagree that there aren’t amazing builds to see, they’re just not so easy to find! now that i’ve explored the game for a fair amount of time ive only recently started to uncover some of the more ambitious and amazing builds! I’m actually kind of surprised it took me this long to find them, and perhaps that is a good thing (?) for long term sticking power of the game. However to your point, perhaps these amazing builds need to be somehow more accessible by the masses!
Here is mine on my thoughts on how to improve prestige!
