If I could be so bold to suggest a modification to the transmog vendor who lets you view transmogs by their rarity. Each individual mog there costing a transmog token (50mp)regardless of rarity has always struck me as a tad too expensive. Especially so when vendors standing directly next to them allow you to pay 2x transmog tokens and permananlty own the item; thus enabling transmog forever at the low cost of 5mp+gold to save the set. Personally speaking this wouldn't deter me from farming the items that are actually obtainable in game in order to lower the cost of transmog for that slot and it would make the stuff i can't get (the more expensive, for mog token only stuff) more desirable. I would suggest they cost gold instead. Perhaps, 25-50-100-200 or something similar.
With regards to the other vendor standing nearby with the Orb of Deception and a small list of other related items could use a little extra stuff. I humbly submit that that is where Path of Cenarius, Path of Illidan and other similar one-use items should be located. I might also suggest that the stack size of those two items if added should be increased to at least 100. When i personally obtained them a couple years ago through what I assume is a removed npc was very, VERY limited in number despite being a mog token to purchase.
Lastly, I previously asked about the modification of the Dire Brew item. It is a very interesting item when modified to simply extend whatever the current transformation is active. To give an example, once a Dire brew has been consumed the buff would still say the same thing and duration would be an hour. However instead of a Dark Iron "whatever" you are blessed with the ability to interact with the best FUN mechanic in the game. Playing the game as something other than yourself. Consume Dire Brew and DBW pops? Enjoy 1hr or whatever of the three procs you got. Consume Dire Brew and farming Netherwing Eggs for that sweet mount? Enjoy 1hr of Fel Orc badassery. There are SO many "temporary" transformations that work incredibly well as actual models for us to fool around with. Time-Lost Figurine is 10000x more desirable when you can keep the Birdman costume for the whole raid and do that sweet arrokan dance along the way

If anything is accepted please let it be the Dire Brew. I don't recall how it was done but it wasn't a game breaker and literally everyone who knew about it was using it. I will champion it as a cause if necessary and do any testing necessary to get working happily.
Thanks for the consideration,
