I was able to farm 207 WSG marks in one day!
Follow this guide step by step:
1. "Aquire" Xelerator 1.4
2. Set the program up, it really isn't too hard to do
3. Make a Trial account ( I'm going to assume you know how to do this )
4. Open up two WoW clients, and log in on both, one with your normal 10-19 character, and another with your new, fresh, trial account.
5. Get your trial account class to level 10 (make sure he's the same faction, unless of course, you'd like to lose the matches)
6. Get both of your characters into the same BG (This can actually take awhile, and some coordination and patience if you're on a shitty PC.)
7. Accelerate the speed on the Trial account window, speed up, get the flags be creative! (But not too obvious, unless you want to make another trial account due to this one getting banned sooner)
8. Win, and get three free marks of honor!
9. Rinse and Repeat
Enjoy your free WSG marks!
