There seems to be some confusion regarding the matter, so allow me to clarify:
As things stand, there will be no revision of the Tiering System.
I agree with most of the points made by
Matthew.
To summarize:
The currently existing system, specifically the 3-A/Low 2-C distinction is both functional and well-understood by most members. Revising it would be cumbersome, since it would require everyone to re-learn from scratch the means to distinguish between the two Tiers. I'll have to see the proposed change to take an incontrovertible stance, but unless there is convincing proof that the current system is hopelessly inaccurate, I am leaning towards keeping the current system.
Arguing that our tiering system is not scientifically accurate is a rather superfluous argument, given that it has been well established that there are already multiple assumptions regarding the system, none of which occur in real life, and are not scientifically accurate, such as the assumptions made regarding the specification of Multi-Solar System level, Multi-Galaxy level, etcetera.
It has been stated, multiple times, and is consensus, that with the tiering system, we are creating categories/tiers on the basis of commonly observed patterns in fiction, and attempting to standardize them by assimilating current scientific theories.
The 3-A/Low 2-C distinction is one such standardization. There are fictional instances where the mass of a universe has been destroyed, without the destruction of its space-time continuum, hence our tiering system's current distinction is required to evaluate such scenarios.
Hell, the entire M-Theory is just that; a theory. It's not scientifically accurate by any stretch, merely scientifically probable. There is absolutely no scientific accuracy regarding Tier 1 (the Outerverse level), and the less said about Tier 0 the better.
I see no reason to throw the wiki into chaos needlessly, and introduce a possible tier revision on the premise of speculative/theoretical scientific accuracy alone.
