I would like to start off saying yes, sandbox tiger has been mentioned before for a few locations, but they were in 2009 and none involved either the old or the new Orgrimmar.
The purpose is this thread is in three parts:
To compile all new uses I can find for sandbox tiger, show an example, and discuss the possibilities behind it.
Possibilities:
Many of us are aware of certain abilities that can be exploited for exploration purposes, but they are limited to class. Sandbox tiger enables not only yourself, but anyone to explore with you as long as its placed within reach. I haven't found anything HUGE yet, as in an exploit, but I have found some neat little places for it to be used. It is my belief that there are many possibilities for this item that are yet to be explored. While most places are accessible with flying now, there are still barriers in locations that only allow ground mounts such as inside buildings, instances and bgs. Note: This item does not work in arena but I am pretty sure it works in battlegrounds, I will have to check in my next one.
The only limiting factor to these possibilities is that it requires one to purchase this item, either with gold(if there is a supplier on your server) or with cash. I believe this is the biggest factor that has prevented not much exploration/exploitation to be found so far with this item.
Example:
There are a few ways to get behind the AH currently in Orgrimmar, but its mainly limited to warriors(heroic leap) and mages(blink). There is also the option of flying in, but it is hard to successfully do as your relying on not being dismounted, which seems to either be random recognition or based off lag. Point being: its not easy for everyone to get behind the AH. This is all common knowledge by searching the forums and I do not take credit for this.
Now to the beefy part. Once behind the AH, simply place a Sandbox tiger near the ledge where other can click on it. They then dismount by pressing the dismount button(I dont get one for some reason), or type /leavevehicle
This allows anyone to get behind the AH, it does not require a group/raid to use. If you have a coordinated group of people, you could easily throw an epic party back there with various items. There is also the option of blocking the AH guys, but I don't really care for griefing people(even though theres numerous AH locations now), and thats probably just asking to get reported.
Sandbox Tiger1
Sandbox Tiger2
Theres also a few levels anyone can get to in the AH with a few simple jumps.
The first is here:
AH Exploration1
You must run into this beam, and eventually you will pop up a little bit. When you do this you are able to strafe jump over the ledge to the area shown. This gets you to level two.
Next you find this box, which is to the northwest side of the auction house on the 2nd floor:
AH Exploration2
Once again use strafe jumping over to the beam shown. It is easy to overjump it so be careful. This gets you to level three.
There is one more level, but I believe the only known way to get there so far is by flying into the AH.
I will be posting my future Sandbox Tiger finds here(I have over 400 charges). In the meantime, will give rep for anyone who manages to get a screenshot of their own epic party started behind the AH or find other cool exploration/exploitation uses with this item.
In the event that I end up getting another sandbox card, I will probably hand it out as well so others(who cant afford one and don't have the option on their server to buy a code with gold) can test them out in various places. But this is highly dependent on me running into more, which would require me to buy the scourgewar TCG packs.
