I feel the merchant in the lv 45 DRk quest is a bit of a jerk. Sure later on he tells us that we actually did him a favor by returning those wares all bloodied. The masked Miqo'te from the allied beast tribe quests is constantly a sleezy jerk. Then there's Kageyama who isn't a great guy who we run into multiple times via the unlock for Kugane Castle, SB Hildibrand and Tataru's endeavor. Don't forget Forelmort the uncle of Jannequinard and Carvallian who is a jerk to us no matter. The I'd bring up Ungust, Lolorito or Laurentiis but they all appear in MSQ. Though Lolorito is also a jerk in twice in the ARR Cul quests.
