I think the main question is more along the lines of, wouldn't those bugs still exist and therefore need to be fixed because of the eternal format?
This just means the bugs are of less quantity specifically in the standard format, but it feels strange for rotations to use the reasoning that it presents less bugs, when those bugs will exist regardless due to the eternal format.
That leads to a lot of us fearing that the eternal format is expected to be more of an afterthought, and bugs addressed less frequently there. Or that we should expect a large spike of bugs and issues in the eternal format essentially on every release due to a heavier focus exclusively on standard.
Yes, the bugs would still exist. That’s why I keep saying rotation doesn’t eliminate the need to address bugs. This is a list of the many reasons the game gets more time consuming to manage over time (which is why rotation wasn’t needed at the beginning but is very valuable now).
New cards being added introduces a bunch of challenges that make the game take more time to develop. Rotation makes some of those issues easier, giving us more bandwidth to manage the others that it does not make easier.
It’s all the same team, as the time we spend managing bugs increases we have less time to do other things. Rotation reduces the time it takes to do some of the other things (not bugs).
