Onto Partnya vs Partnyer. They're basically the same thing. Using the long a, or in this case yā (ャー) can also be romanized to a "er" or "yer" similar to how super is スーパー or sūpā. Despite it all, Capcom still decided to use partnyer on the official G5 website, even though they could've used partnya. Why would they go with that? http://www.mhf-g.jp/preview/g5/pc/index.html#/partnyer/0

I've heard the argument of "the people that make the games and the ones who make the site are different", but that's a silly argument. Obviously it has to still be approved by Capcom. It's still the official term, romanized how Capcom chose, which is why we use it.

I swear, there will never be an end to arguments with Japanese names since there's way too many ways to romanize things.
