Classic Revisiting TBC in the Era of Dragonriding

I'm doing some holiday questing and I had almost forgotten Exodar and Silvermoon still somehow do not have flying and I wanted to see if anyone had an idea as to why, hopefully something more than "they just never added it". Is it a technical issue perhaps?Thanks and looking forward to your insight! via /r/wow https://ift.tt/wpCgcOr
