:-/ as with any other wiki, it takes a multitude of people for it to be done correctly. I work hard to keep Paladin as up to date as possible, but yeah, it's hard when the other classes aren't around to pick up the slack.
It gets hard when there are slightly less popular classes out there.. I remember times when there were practically no DreadKnights or Necromancers. Just take care of your class the best you can, and if you have any friends who play classes in desperate need of updating... well, yell at them. Aside from that there's not much we can do, and I don't really want to waste an admin's time working on the wiki when it's something a player can take care of, if they're willing to put in 30 seconds of effort.
