In World of Warcraft, you get honor for every market you deliver. Since you get more honor per 10th level, this can be easily bugged or exploited by getting like 20 markets at lvl 19, then grind to level 20, and when you deliver them, you will get more honor, because the server thinks you've played on a BG with level 20-29
Example:
I play WSG 10-19. Horde wins.
I get 3 marks of honor. If I deliver these, I will get, for example, 100 honor. But now, if you get level 20 and still have those from level 19, you will get for example, 150 instead of 100. I don't know if this has been patched yet. But this does really work. The idea with this, since you will mostly own the BGs at level 19, you get many markets which can be delivered later for more honor
