Although I don't believe conjurers to be overpowered because I know lots of ways to neutralise of kill them with several classes, they really do seem to own necros.

It's something I've noticed too. But I think if I played a necro again I might be able to beat conjurers too, using similar tactics to those most warrior specs could. I can't tell until I try it though.

Your tactics when you raided with a certain invoker (not Tilaen) were probably the best a necromancer has tried to date against me. Having played this class has shown me what I should have done with all the others though, Manarei's assassination of me being one example or how to get round a conjurer's strengths.
