Cool things to do with hacks?

[Xiandri]

I have been using hacks to get flightpaths for my new alt. I managed to get the hyjal flightpath at level 12, and I was also used it it instances to skip content and stuff.

I was wondering, does anyone have any other cool things I can do with the hack? like, for example, on Dire Maul you can use it to skip loooads of trash and get to the boss straight away, and you can do it on Stratholme and BRD too

I was also thinking of NPCs that sell things e.g the npc in winterspring who sells the companion pet

And I thought about using it to fly under the ground in gurubashi arena so i can ninja the treasure box (not tried it though)

What other stuff can you do with hack?
