Well I run 3 necros in my group. I use KissAssit for them. Using KA I have found that I can specialize my necros to do different tasks. Yes you do have to have a working knowledge of what the spells/dis/AA do and how to use them. Also you need to understand the different sections of KA and how they work to get a feel for how to run the necro with the group setup. Once you begin to see how KA works with your group then the fun begins.
Example: set your camp up in an area. set the pets to guard the camp. pull with a darkness spell. mob hits camp and pets jump on it. hit it with dots and then fear the sucker and let pets destroy it. Adds come to help out the mob and you can send pets to keep them busy while you work on the first one.
In this example my group is SK, Necro, Necro, Necro, Bard,Shaman,Mage. That gives me 5 pets (with mage weapons and gear for all)
So all in all I like the use of KA for the group.
