Not really. If you have a ceiling you lose the ability to check for the most egregious outliers.
If you assume a ceiling of 1k and you have a build that can do 1.2k now, it will be capped at 1k. If you have a build that can do 10k, it will be capped at 1k as well. You don’t have a way to find out that the 10k is obviously super broken and needs to be super-nerfed.
I view corruption as simply a new game+. You finished the game (meaning, you achieved whatever goals you had) and instead of leaving the game and returning in 3 months, you can keep pushing, if you feel like it.
It’s not mandatory, it doesn’t really give you much more, it’s just something to do if you want to keep min-maxing.
Corruption would make sense as a NG+ if there was enough of a game up until that . You can finish the whole story and monoliths within what, 8 hours of braindead playtime for a semi-experienced player? That in the context where "the game starts at corruption difficulty " sprayed all over here.
Diablo 3 made infinite scaling work because with how sets and uber items were designed to work, there was enough of a power spike and adrenaline rush that you felt accomplished and had that itch to see how far it could push you after completing that set for the 10000x power spike and then getting it with perfect rolls too.
We got none of that here , again it’s about well defined boundaries within which you can see your efforts reflected. 99% of players are not Raxxes that farm the game for stream content or out of a natural obsession to find broken builds, these are natural born quality testers but not players. If the boundary is 0-infinite, it makes all your efforts feel null against the threat that the upper 1k unofficial ceiling can always go higher and there’s nothing special separating where you’re at , from the rest.
You can easely nerf overpowered combos if they smack end content within seconds. You just tone it down and don’t care about the 10k since you want it to feel good and challenging at 1k. You can bother with it at 10k when you raise it up to that.
A perfect example of how currently trying to balance around infinite scaling is terrible is the WraithLord helmet, an item clearly designed to push higher than any build before could. But what it does it nulifies anything before it, why would anyone pick any other minion build when a simple helmet makes you a minion that does 100x more damage ? It throws out the window any balance because it’s designed to test how far it can push high corruption with no concern for below 500corruption at least.
Because it is fun to play any other minion builds that is not meta and make it somehow working? Is it that hard to understand that some people just like playing “so cold meme” builds and having pure fun with it? Whats the difference if I make it to 700cc than to 1000cc or even 3000cc. Is it that fun just opening boss-loot-boxes, ignoring most mobs and bosses mechanics? You call it fun? For who?
Just my 2 cents
