@necrogeist said in New Companion Errata:
it's difficult to tell whether the increase in mistakes in Vintage can be attributed to the failure to adequately test for Standard or simply to the push to increase Standard's power.
We know that historically for most cards to make it into the Vintage world, they have to be pushed because vintage already has all the pushed cards. This is not at all a matter of them pushing because the power level on many of these cards is moderate in standard. Mystic forge was never going to be a power house in standard, and the cards that are strong in standard almost never transition to eternal formats.
The issue is that they are not pushing power so much as they are pushing mechanics in new directions. Companion was very much a new mechanic that did not have any real parallels in magic. Planeswalkers with enchantment like statics was very much a new mechanic. Even cards that are problematic elsewhere like once upon a time were new mechanics. That is not to say they are not also pushed in power, but there were not a lot of if any comparable cards to compare them too.
Have a look at the rehashed old mechanics. We don't have any cards that are issues because of cycling, because they know some of the upper and lower limits of that. Amass was a fancy token generator, plenty of cards that do that.
I'll use the development example again. I have a line of copy in my webpage. I want to change the color of it. I know from experience that there are only so many things that can wrong, so I do not need extensive testing to make sure it works everywhere, as I can with a high degree of confidence be sure it will.
It behooves me as someone who makes a product to undertake the proper amount to testing I need to take to make sure that product is supported on all the other platforms that my company supports. If you think about the various official and sanctions formats of magic, those are in effect the companies platforms. Shouldn't it behoove them to either drop support for the format that they are not properly supporting anyway, or to test for it at a rudimentary level?
