Twinking is the fine art of taking your character to levels far beyond what he/she should be able to do at any given level. For example, a Rogue twink, at 19, with 2,000 HP? It’s been done.
The [tag-tec]Warsong Gulch[/tag-tec] Battleground (Capture the Flag) has a level 10-19 bracket. Naturally one wants to be level 19, otherwise rapid doom will happen. Then one needs that little edge over the other 19s…
AzerothNow.com has a killer twinking guide for those level 19 Rogues bent on mayhem and slaughter in Warrsong Gulch (and maybe a duel or three.)
So you’ve done your dailies - everyday, you’ve cleared Heroics and Karazhan for Badges until your eyes bleed, maybe you’re even utterly tired of farming Illidan every week or wiping on Kil’Jaeden. But what now? Level another character? Cancel your subscription until Wrath?
Well, I have your solution: why not create a lvl 19 Twink Rogue? But what is a lvl 19 twink Rogue, you may ask. The simple explanation is that they are characters with the best possible gear for their level (including enchants), whose purpose is PvP, and their playground is the 10-19 bracket of Warsong Gulch Battlegrounds.
