Would it be possible to have the PTS without the main story quests or any of the quests for that matter unless they need to be tested for some reason? Also, is there a way to maybe leave out some of the veteran or hard mode mechanics out? This way there aren't a bunch of guides out before anyone really gets to play the game. FFXIV doesn't even have a PTS, but I understand the need for one for most games. My suggestion is to just help preserve that sense of discovery and wonder when you don't know what the devs have up their sleeve. I know I could ignore the internet, but that is really hard to do in this day and age. Anyway, just a suggestion.
My apologies if PTS is already built this way....I have stayed away from it as much as I can, but just wanted get the suggestion out there, just in case.
