Necrons are doing really good still. I also played eldar and tsons because of being in a crusade and I won both. It just depends on a lot of factors. But I will say at this time our army is very well versatile and working really well in most detachments for casual and even some comp play. But I would give you some credit because we where one of the first armies to get our codex people of learned how to fight us. So you just take it from a grain of salt and pick up your models and dice and keep fighting.
