What the FUCK is Horizontal progression supposed to look like in practice...

It shouldn't be hard to answer a simple question, calling someone an idiot isn't answering. Yas Forums turns autistic when someone asks a simple question "What's the point to doing a dungeon if it doesn't give you anything for completing it." and then Yas Forums responds with insults. The intelligence of this board really declined.

>But horizontal progression gives you no reward.
No, it's fun to try new things.
>You play better, but what do you get in return?
Fun.
> You get nothing,
No,
>all you're doing is playing better for no reason
playing better is fun.
>but what's the point to the build variety if there's no reward for going a particular build?
Trying new things and mastering them is fun.
No
