Yeah necros used to be able to Tap on anything.. In 99 I watched a very low level Necro on Live kill a Hill Giant in North Karana once. He had the giant hung up on the Wizard spire, running in place (before they changed things so the mob would warp through the geometry). He'd cast Life Tap and sit down to meditate. It took him forever but he eventually won and got the kill..

Regarding Necros in end content Raids. They are most certainly needed. As mentioned, they are a supporting class primarily. They will be twitching clerics and helping with CR's. You should define what it is that you are interested in for end content raids. If you want to be more involved in the action, roll a melee class. Remember though that you have a LOT of time ahead of you to get to the end content so pick a class that you will enjoy for that ride instead of worrying over the end raiding stuff..
