Just trawling the paladin forums and it now seems that paladins dps-ing in karazan is now a very much viable option. A lot of paladins are very happy with the adjustments made to the prot and ret tree and we now seem to be of some use. In some threads I was reading that pally were even topping the damaging meters on some of the bosses. I might like to try it out when we're a bit more comfortable in Kara, seeing as we have an abundance of healers.
