Still trying to earn a bit of rep. So I figured I would post about my usual trick. Its simple and highly easy to do. Its still active with patch 2.4.
This of course can only be done by horde since its a horde only quest. It starts in Sen'Jin Village where you do a line of quests and are able to talk to a witch doctor in training who places random stuff on you.
Ghost
Blows you up in the area
Growth -->what we want
Turns you into a snake
Turns you into a chicken
Makes you drunk
We want to do growth. If you talk to him, you notice the buff is always random, but you can get good luck and see that growth will not stack if you get it one after the other, it just refreshes the buff.
Growth lasts for 5 minutes.
So here is the trick. Once you get Growth, log out, then back in, and try for the second. Once you grab the second one, you will get 2 buffs of Growth and be double the size.
This stacks with Firewater and Growth Pots.
Remember, this is only a 5 minute buff. If you logged back in after getting the first, you are still bing timed, even once you grab the second one. So you can have a buff for 5 minutes and only have 30 seconds on the second one. This is more about luck.
Its also good to have a warlock with friends in Orgrimmar or where-ever you wish to go, ready to summon you.
Note: ZONING (IE heading to shatt, or Eastern Kingdoms, or inside an instance) will remove the double buff. Its best to stick in the Kalimdor area to keep the full effect.

Also, I apologize if this is a repost. I did a search and found nothing on it unless it is worded completely different.
