By all accounts, Simple Domain should neutralize Infinity.

The explanation given for Amplification is that it's the area of a domain that allows infinity to flow through. All of this should apply to Simple Domain, it's a domain with no cursed technique imbued just like Amplification. They also both share the CT weakening effect, further showcasing they're extremely similar in practice.

Yet I've been told being wrong without ever being given justification to think this.

Is it a case of "Never stated" where it should logically work but never confirmed otherwise, or am I making a critical mistake in my judgement missing something?
