i got a blue response from GC that said the meta would affect everything, but that was 3 months ago so who knows. lemmie try to find it.

he states 3 separate times that ALL ARMOR will be affected by the meta, i think they realized even that would be too powerful i would gain about 500 more armor if that were still the case.
