Agh well, here is worthless piece of junk of a guide. It didn't fit in the scam section nor the exploit section so i guess i can dump it here
Currently there is a quest 'Raining Down Destruction" that gives you Gift of the Giants which makes you bigger, actually it makes you huge.
Now you can use this in combination with Gigantic Feast and Winterfall Firewater (or Elixir of Giant Growth) to make you one big rallying mad man (or a gnome that finally can equalize to the size of their Night Elf Allies)
Nw if you got a Shaman friend available you can be even bigger with Heroism.
During Hallowween you can also eat the Candy that makes you Orange and Big (Hallow's End Candy - Spell - World of Warcraft)
You can then mount of and ride on ride on your mighty steed crushing buildings and stuff.
Have fun
PS: Yes this is useless, but funny to see, i'll post some screens if a few minutes.
