19s have been unplayable since 4.0 i feel, and certainly wotlk was not even there peak, id say bc was a lot more interesting, less bursty and more balanced perhaps. (hunters always being top tier). 85 pvp is SO SO much better that I really think playing twinks has become only of sentimental value. I just dont see the point of putting oneself through a wsg where its clear that stacking hunters is BY FAR the best tactic, and the one prevalent in PuGs.
I personally, and i know others who feel the same, would only ever play 19s again on a BC/wrath private server, as since the launch of cata, blizz has adopted the policy that leveling 1-85 needs to not be daunting, ie. insanely overpowered abilitys on most classes and just terrible terrible pvp resultantly.
tl;dr twinks are fkn dead and buried, play 85s, its a lot of fun.
