Idk why NA BR fight tho, like it's literally just the Americas. But mind you theres much more pple actually respecting the regions rather than hating on each other. It's literally just a handful of pple on forums that trash talk.
APAC consists of SEA/SA/OCE/KR/JP. None of these regions ever won an event so we keep our mouths shut for the most part. At least JP and KR do, there are some toxic SEA fans but overall the vibes are good! Every region has their good eggs though :)
