Fellow collectors, I've noticed something in this expansion, well I noticed it in MoP, but I figured it was just a one-off, but it happened again in WoD. There are no mounts to be collected from dungeons. While sure, there are plenty of mounts to find in both MoP and WoD, I find it a bit disappointing that I have no desire to return to older dungeons to farm for a mount. Even at level 90, I went back and ran Vanilla, BC, WotLK, and Cata dungeons to grab some rare mounts. However, MoP and WoD don't have any.
Vanilla - 1 - Rivendare's
BC - 2 - Hawkstrider, Ravenlord
WotLK - 1/2 - Blue Proto-Drake (maybe Bronze Drake if you want to count it, but it's a 100% drop)
Cata - 4/5 - Armored Raptor, Swift Tiger, Drake of the North Winds, Stone Drake (again, Battle Bear, but it's also a 100% drop)
Now here's the issue.
MoP - 0* (There was a datamined mount back in MoP beta, the Heavenly Jade Cloud Serpent (same model as Yu'lon) which was rumored to drop from Lui Flameheart, the third boss in Temple of the Jade Serpent, however, this never happened...)
WoD - 0
WoD had many great options for dungeon mounts. The Skyreaver from the store would have been a perfect drop off Skylord Tovra in Grimraid Depot. This is going into controversial issue of store mounts so I'll avoid that, but it was just an example.
It might just be me, but I miss grinding mounts everyday. The current system in WoD is garbage for players like myself who work full-time and don't get much time to play. I don't have time to sit around and wait for a spawn for 8 hours.
