I don't play nearly as much as other people play the 19 bracket, at least not anymore, but whenever I get bored and hop on my 19 pally I can own it up pretty hard, in both damage, flag runs, and flag returning. I had someone awhile back whisp me when BC was first introduced and BE pallies were starting to pop up everywhere, most of them being clueless at the time as they were new to the class, anyway I got whisped as to how I was doing so well in a bg and not being fully twinked, I simply replied because I had been doing it for years on ally side. If you know how to play the class I think "retadin" at 19 could work very effectively and I've seen it in action personally.
