First, thanks to Firaxis for working hard to get a patch out so soon. Fixes for the gpt and corruption issues will be greatly appreciated.
Second, it must be gratifying for the programmers to know that any changes to the C3C will instantaneously be assessed by an international team of scientists. There are probably more Phd's surreptiously working on the C3C rng issue right now than on super-string theory or global climate change.
I see that most of the theoretical work has already been done, perhaps later I can develop varaince estimators for the proposed combat system. I suggest that we link all our computers together in parallel via the internet and hence create the world's largest supercomputer.
I too share the concern that changes to the RNG for combat could have quite substantial effects on gameplay and strategy. I'm not sure what the intent of the rng change is. If the concern is merely to avoid the spear beats tank problem, then there are many ways to fix this without dramatically altering gameplay. If the concern is to avoid frustration with relatively improbable, unfavorable combat outcomes by making combat more predictable, I fear that the proposed "fix" will have numerous unintended and negative consequences relative to strategy. Personally, I like the uncertainty associated with never quite knowing where the fine line is between crushing victory and humiliating defeat. The possibility of failure is what makes victory sweet. Many studies have show that rats and humans are FAR more interested in success when it is uncertain (e.g., gambling) than when it is predictable, even if the expected probability of success if the same.
Opinions might change if people actually "test" the new system, and that can be sorted out through play-testing . . . BUT, I think the "tragedy" (just a game, right?) here would be if people did not use the patch because they felt that the negative consequences of the rng fix outweighed the obvious and universally welcomed

benefits of the gpt/corruption fixes.
So my two cents is, include the proposed rng fix in some form as a flag or a preference, but don't force people to accept that rng "fix" to take advantage of the gpt/corruption fixes. Then, let the community decide how to deal with the rng issue.
