So I got nearly 40k prestige points when I finally got to tier 25, which makes multiple presiges rather unnecessary. Personally, I think it took me a total playtime of like 20 hours or more to AFK to get from tier 20 to tier 25.
I think that if you removed the tier requirement and changed the prestige points earned to be the max tier you reached or something then that would make multiple runs something worth doing. I dunno, there's lots of different ways you could balance that out.
The orbs orbiting the magnests is pretty cool though!
