Uber geared twinks exist in most brackets, 15-19, 25-29, 35-39, 45-49, 55-59 and so on.

But nothing even compares to the bracket of 75-79, nothing is even close. The Cataclysm BoE greens and blues are better than ICC Heroic raid gear and you can use it against lvl ~75 quest geared people.

Imagine a team of 5 cataclysm geared characters at lvl 79 - I cant think of anything close to being as OP as this. Im tempted to level up something, should be incredible fun! =)
