I was thinking, what will happen to him once the event, where it is obtained from, has ended? Does anyone have an idea? because, if it is going to be unobtainable, i'd strongly suggest to farm up as many of them as possible, instead of investing your Mojos in gear.
The 5.1 area event questline has run its course and been over for awhile and you can still obtain that pet and mount. I know blizz has said repeatedly they don't like removing items after all the rage following the Plagued Proto-Drake removal back in WOTLK. I wouldn't expect them to make such a minor item unobtainable. Especially a tradable one at that.
Though you never know. Ill have a few just to play it safe.
it could be like those launch event types where they remove it from the game after a month similar to AQ event or cata lead up event... it certainly wouldnt be the first time they make a pet unobtainable after a certain time... I mean there is the vampire batling though it is bop...
Patch 5.3 introduces a new world event, Battlefield Barrens, that explores the conflict between the Alliance, Horde, and Garrosh. There's a ton of stuff to do and collect as part of this event--but it's only around for a limited amount of time.
i've got a hard time believing that the pet will become readily available at breanni's just like that. my belief is that it will either disappear or turn into some rare drop. even if the vendor would stay, we still would need mojos to get it, which is only obtainable through the quests. those are almost certain to go away.
