The minion was going for 2-3 million gil last I looked on Ultros.
I'd rather give the PVP a try than wait for that to come down. I need to grind marks anyway to buy the PVP songs since those were also going for millions of gil last time I checked the board.

Changing the drop to wins only wouldn't affect how I play, it would just make me have to play even more matches to get what I want. I do try my best the rare times I PVP, my best just isn't very good (yet).

If the minion is confirmed to drop from the unrated mode I'll happily farm that as I don't wish to bring down more serious competitive players on my team.
