I don't understand why FFXIV is so offended by pre-mades.

Pre-mades exist in every game with multiplayer. When you're a PUG group against a premade you should try harder to win. (I solo queue mostly, sometimes with 1 other friend or with my wife).

The problem with FFXIV PvP is not pre-mades it's people giving up if the fight is "too hard" or "we're losing, what's the point" or " I'm just here for xyz reward and don't actually care about winning anything."

The other issue is that individual contribution means very little. It takes forever to run anywhere, too much PvE focus in PvP games and PvP rewards the zerg vs skill.
