Wolves' Den, the first genuine player versus player combat in the FF series"

[Shirai]

anyone with a valid opinion

An opinion, by default is never valid nor invalid.
It is subjective to what you agree or disagree with thrrefore a valid opinion does not exist it's either opinion or fact.

Pvp is player versus player, wether it is instanced, through a minigame or open world does not matter.
This has nothing to do with opinion, this is fact.

That your opinion is that they did not implement it the way you wanted does not change the fact that it is still pvp.
