all the OG twinks went to wotlk 19s Mankirk (H) and Pagle (A). The noobs stayed in retail and do PvE epic gear farms. BG and Arena scene sux also on retail. If you're looking for good games like back in the day head to wotlk, all the talent is there. Retail is a cesspool of non-talented players.

Hardly any talent when you have 3 spells on your bars in 19s wotlk
