Twinks are mainly used in PvP fighting and Battlegrounds. Twinks obtain their items through rare drops, drops off of bosses in instances , rewards from quests that are difficult to complete at their level, and from the Auction House. Twink items on the Auction House can be expensive and twink enchantments can only be performed by high-level characters. However, there are examples of self-made twinks that generate the necessary gold from Auction House trading or other in-game methods.

I was just thinking that twinking has been around since Vanilla in one way or another. Twinks have a fairly legitimate claim on being able to BG at the same level as much as they want. Blizz would have to change their matchmaking to make sure that either no side had a twink, or that both sides had the same number of twinks. Give the twinks a buff that highlights them to their own faction, that way levelers that are at risk of getting ganked can run to their twink and rally around them. I can see Blizz not being happy because that would require them to put actual work into the matchmaking process to make it work. This is already what I saw before queues were separated.

Twink WoW - A low-level character made more powerful by higher-level characters, usually through gifts of armor and weapons that the character would not normally have at such low level. Also used as a verb to describe the act of giving low-level characters powerful items uncommon at their level. A typical twink, armed with heirloom sword and shoulders. Notice, though, no weapon enchants.
It is those who play on trial account for free and so-called veteran accounts, you can play for free up to level These players get the best gear you can get for the level and have it all enchanted, just so they can kill those who want to level up. I suggest you to put em with the other ppl that want to play at just that level.
